What Is DGL Licorice and Why Does the Form Matter?

If you have been searching for a natural gastritis remedy that goes beyond antacids or proton pump inhibitors, you have almost certainly come across deglycyrrhizinated licorice — better known as DGL. But the name alone raises a fair question: what exactly was removed, and why does it matter for your stomach?

Licorice root (Glycyrrhiza glabra) has been used in traditional medicine for thousands of years to soothe digestive complaints. The problem with whole licorice extract is a compound called glycyrrhizin. When consumed in significant quantities, glycyrrhizin raises blood pressure, causes sodium retention, depletes potassium, and can trigger a condition called pseudohyperaldosteronism. That makes standard licorice root extract a poor choice for long-term daily use, especially for people managing chronic gastritis who need a supplement they can take consistently.

What remains after that removal process is a concentrate of other bioactive components — primarily flavonoids, saponins, and polysaccharides — that are believed to be responsible for DGL's mucosa-supporting and anti-inflammatory properties.

The liquid form — sold as DGL drops or a liquid DGL supplement — takes this one step further. By delivering the active compounds in a pre-dissolved, water-based solution, liquid formulations may be absorbed through the mucosal tissue of the mouth and upper GI tract faster than a tablet that must first dissolve in stomach acid. For people dealing with active gastritis, that speed of contact with inflamed tissue matters.

How DGL Drops Work for Gastritis

Gastritis, at its core, is inflammation of the gastric mucosa — the protective lining that coats the inside of your stomach. Whether it is triggered by Helicobacter pylori infection, chronic NSAID use, alcohol, stress, bile reflux, or autoimmune processes, the common pathway is a compromised mucosal barrier that allows stomach acid to reach and irritate the underlying tissue.

DGL's proposed mechanisms of action in gastritis address this problem from several directions simultaneously:

Stimulating Mucus Production

The flavonoid compounds in deglycyrrhizinated licorice for stomach lining support appear to stimulate the secretion of mucin — the glycoprotein that forms the protective mucus layer over gastric epithelial cells. A thicker, more robust mucus layer physically buffers the stomach wall against acid and digestive enzymes.

Promoting Mucosal Cell Regeneration

DGL may support the proliferation of mucosal epithelial cells, helping the stomach lining repair micro-damage faster. This is particularly relevant in chronic gastritis, where ongoing low-grade inflammation can prevent the lining from fully healing between episodes.

Anti-Inflammatory Activity

Several of the flavonoids found in licorice root — including isoliquiritigenin, liquiritigenin, and glabridin — have demonstrated anti-inflammatory activity in laboratory studies, reducing the production of pro-inflammatory cytokines. In the context of gastritis, this may help calm the underlying inflammatory response rather than simply masking the symptoms.

Antioxidant Support

Oxidative stress plays a documented role in gastric mucosal damage, particularly in H. pylori-associated gastritis. DGL's antioxidant polyphenols may help neutralize reactive oxygen species at the mucosal surface.

What DGL Does Not Do

DGL does not suppress acid production. It does not function like a PPI or an H2 blocker. This is an important distinction: if your gastritis is driven primarily by excess acid, DGL alone may not provide complete relief, and combining it with acid-reducing medication may be more appropriate. We cover that combination in the section on taking DGL with medications.

What the Clinical Research Actually Says

One of the most important things you can do before purchasing any herbal gastritis supplement is to look past marketing language and read what the actual studies found. Here is an honest, structured summary of the current evidence base.

The GutGard® Phase III Trial (2025 Review)

A 2025 Nutrients review summarized a phase III randomized, double-blind, placebo-controlled trial of GutGard®, a standardized deglycyrrhizinated licorice extract. The trial enrolled 200 participants and ran for 28 days. Results showed statistically significant improvements in quality of life and earlier relief from heartburn and regurgitation compared with placebo, with benefits emerging as early as day 7. This is one of the most methodologically rigorous trials available for DGL and GI mucosal conditions.

Chronic Duodenal Ulcer (Uncontrolled Trial)

An uncontrolled trial in 32 patients with chronic duodenal ulcer reported healing signs in all cases. Substantial improvement was observed in 56% of patients by week 12, rising to 78% by week 16. While the lack of a control group limits the conclusions that can be drawn, the magnitude and consistency of improvement is clinically notable.

DGL Plus Antacid vs. Cimetidine for Gastric Ulcer (Single-Blind Trial)

A single-blind randomized trial in 100 volunteers with gastric ulcer found that DGL plus antacid was as effective as cimetidine (an H2 blocker) after 6 weeks. This is particularly interesting for patients who want to explore alternatives or adjuncts to pharmaceutical acid suppression.

The Double-Blind Gastric Ulcer Trial

A separate double-blind gastric ulcer trial reported no faster healing versus placebo. Importantly, no side effects were observed in the DGL group. This trial is sometimes cited as evidence that DGL is ineffective, but researchers note that the formulation, dose, and timing variables differed substantially from trials that showed benefit.

2025 Systematic Review: 9 Trials, 618 Patients

A 2025 licorice review noted a systematic review encompassing 9 trials and 618 patients. Ulcer-healing and pain improvements were reported numerically across the trials but did not reach statistical significance in the pooled analysis. This underscores that the evidence for DGL is suggestive and promising rather than definitively proven — a distinction worth keeping in mind as you evaluate your options.

December 2024 Comprehensive Review

A December 2024 review article revisited the older ulcer and reflux datasets, including the duodenal ulcer findings and the gastric ulcer trial comparing DGL plus antacid with cimetidine. The authors' general conclusion was that DGL demonstrates a favorable safety profile and biologically plausible mechanisms, while acknowledging that large-scale, high-quality primary trials remain limited.

The Honest Bottom Line on Evidence

The clinical picture for dgl licorice gastritis use is this: the evidence is more robust than for many herbal supplements, with multiple human trials across several decades and a well-characterized mechanism. It is not as robust as the evidence for PPIs or H2 blockers for acid suppression. For gastritis specifically — as opposed to ulcers or reflux — the data is extrapolated rather than directly studied in large controlled trials. That gap matters. DGL is most appropriately viewed as a mucosal support strategy, particularly useful for people who want to reduce reliance on pharmaceutical acid suppression, or who are dealing with gastritis driven by mucosal vulnerability rather than pure acid excess.

DGL for H. Pylori: Separate Question, Real Data

Approximately 44% of the global population carries Helicobacter pylori, and it is the leading single cause of chronic gastritis and peptic ulcer disease worldwide. If you have been diagnosed with H. pylori-associated gastritis, you are right to ask whether dgl for h pylori is a viable option.

The short answer: DGL is not a replacement for H. pylori eradication therapy (triple or quadruple antibiotic regimens), but it may play a meaningful supportive role.

Several of the flavonoid components of licorice root — particularly isoliquiritigenin, licochalcone A, and glabridin — have demonstrated antimicrobial activity against H. pylori in laboratory (in vitro) studies. These compounds appear to disrupt the bacterial membrane and, in some studies, show activity against clarithromycin-resistant strains.

Importantly, DGL's ability to stimulate mucus production and reinforce the mucosal barrier may reduce H. pylori's ability to adhere to gastric epithelial cells in the first place. Bacterial adhesion is a critical step in H. pylori colonization, and a robust mucus layer physically impedes that process.

What this means practically: if you are undergoing standard H. pylori eradication therapy and looking for adjunctive support to protect the stomach lining during and after the antibiotic course, dgl drops for gastritis represent a reasonable, evidence-informed choice. If you are trying to manage H. pylori without antibiotics — perhaps due to antibiotic resistance or sensitivity concerns — DGL-containing herbal protocols have been explored in integrative medicine contexts, but this should be done under the supervision of a qualified clinician who can monitor your bacterial load with follow-up testing.

DGL Drops vs. Chewables vs. Capsules: Which Is Best?

The form of DGL you choose has practical implications for how well it works and how reliably you will take it. Here is a clear breakdown.

DGL Chewable Tablets

The traditional DGL delivery format. Chewing the tablet mixes DGL with saliva, which proponents argue begins mucosal contact in the esophagus and upper stomach immediately. They are convenient, taste reasonably palatable (most are slightly sweet), and have the longest track record in research settings. The drawback: they are not always easy to take discretely, and some people find the texture or taste unappealing.

DGL Capsules

The most convenient format. No taste, easy to swallow, familiar to anyone who takes supplements. The key limitation: a capsule must physically dissolve in the stomach before its contents can interact with the mucosa. For conditions involving the esophagus or upper stomach, this may mean less direct mucosal contact compared with chewables or drops.

DGL Drops (Liquid DGL Supplement)

Herbal drops for gastritis offer a distinct set of advantages:

• Speed of absorption: A liquid delivered sublingually or swallowed directly can make mucosal contact within seconds. This makes dgl licorice fast acting claims more achievable in drop form than in capsule form.
• Dose flexibility: Drops allow precise dose adjustment, which is useful when titrating up from a lower starting dose or when following a practitioner's specific protocol.
• No fillers or binders: High-quality liquid formulations often have shorter ingredient lists than tablets, which is relevant for people with sensitivities to excipients.
• Suitability for sensitive stomachs: People who struggle to swallow tablets or capsules due to esophageal sensitivity or active gastritis find drops significantly easier to take.

A dgl licorice 60ml bottle is a common retail size for liquid formulations, typically providing 30 to 60 days of use depending on the dose — making it a practical and economical format.

The trade-off with drops is taste (licorice flavor is not universally loved) and the need to carry the bottle if you take doses outside the home.

Which is best? For active gastritis where you want maximum mucosal contact and fastest onset of relief, DGL drops have a logical pharmacokinetic advantage. For long-term maintenance once symptoms are controlled, capsules may be more convenient. Chewables represent a middle ground with good evidence.

How to Use DGL Drops: Dosing, Timing, and Duration

Getting the dosing right matters. Here is a practical framework based on current regulatory guidance and available clinical data.

Established Dosing Range

Health Canada's listed adult use range for DGL is 380–1,520 mg three times daily. The three-times-daily frequency is important: it aligns with the biology of gastric mucosal turnover and ensures that protective compounds are present in the stomach during the three periods of greatest acid exposure — before or between meals and at bedtime.

Note that this is the range for the dry extract equivalent. For liquid DGL drops, the label will typically provide the equivalent dry-weight dose per serving (e.g., "each 1 mL provides X mg DGL extract equivalent"). Check the specific product you are using and match it against this range.

Timing

• Before meals (15–20 minutes): Taking DGL before eating allows the mucosal-coating effect to be in place when food — and the acid surge that follows food — arrives.
• Between meals if symptomatic: If you experience burning or discomfort between meals, an extra dose may provide relief.
• At bedtime: Particularly relevant for people who experience overnight or early-morning gastritis flares, or those with concurrent reflux.

How Long Does DGL Take to Work?

Based on the GutGard® phase III trial, symptom improvements were observed as early as day 7, with continued improvement over 28 days. In practical terms:

• Acute symptomatic relief: some people report reduced burning within hours of the first dose, likely due to the direct mucus-stimulating effect.
• Meaningful, consistent improvement: expect 1–4 weeks of regular use.
• Full mucosal support benefit: 4–8 weeks of consistent use is the typical protocol in clinical settings.

Duration of Use

DGL is generally regarded as suitable for both short-term (4–8 week courses) and long-term daily use at recommended doses, given its favorable safety profile. If you are using it to support recovery from an acute gastritis episode, a structured 4–8 week course makes sense. If you are using it as part of a long-term maintenance strategy alongside dietary changes and stress management, longer use is clinically reasonable.

Safety, Side Effects, and Who Should Avoid DGL

DGL's most important safety advantage over standard licorice is the removal of glycyrrhizin — the compound responsible for the blood pressure, sodium retention, and hormonal side effects associated with licorice overconsumption. When glycyrrhizin is reduced below the 3% threshold, the principal mechanism of toxicity is eliminated.

Known Side Effects of DGL

At recommended doses, DGL is well tolerated. The double-blind gastric ulcer trial noted no side effects in the DGL group. The phase III GutGard® trial reported a favorable safety profile over 28 days.

Potential minor effects at higher doses or in sensitive individuals may include:

• Mild nausea on an empty stomach (taking with a small amount of food or water usually resolves this)
• Loose stools at very high doses
• Allergic reactions in people with known sensitivity to legumes (licorice is a member of the legume family)

Who Should Exercise Caution or Avoid DGL

High blood pressure: Even DGL products tested below 1% glycyrrhizin are generally considered safe for people with hypertension, but if you are on antihypertensive medications, monitoring and physician oversight are advisable.

Pregnancy and breastfeeding: Licorice in any form — including DGL — is not recommended during pregnancy. Animal studies have raised concerns about effects on fetal development, and the safety data in human pregnancy is insufficient to establish a safe dose.

Hormone-sensitive conditions: Estrogen-sensitive conditions (certain breast cancers, endometriosis) warrant caution due to the phytoestrogenic activity of some licorice flavonoids. Discuss with your oncologist or gynecologist before use.

Kidney or liver disease: Reduced clearance of bioactive compounds may increase effective exposure. Use under medical supervision.

Children: Pediatric dosing for DGL has not been well established in clinical trials. Consult a pediatric practitioner before use.

Can You Take DGL With PPIs, H2 Blockers, or Antacids?

This is one of the most common practical questions from people already managing gastritis with pharmaceutical therapy.

DGL With PPIs (Omeprazole, Lansoprazole, Pantoprazole, etc.)

No pharmacokinetic interaction has been documented between DGL and proton pump inhibitors. Since DGL acts on the mucosal barrier rather than on acid secretion, the two approaches target different aspects of gastritis and can be used simultaneously. In fact, the logic for combining them is sound: a PPI reduces the acid load while DGL supports the healing of the mucosal layer. Many integrative medicine practitioners use this combination during the transition phase when patients are reducing PPI doses.

DGL With H2 Blockers (Famotidine, Cimetidine, Ranitidine)

The single-blind trial comparing DGL plus antacid with cimetidine found equivalent efficacy at 6 weeks — suggesting that DGL can potentially serve as an alternative rather than requiring co-administration. If you are on an H2 blocker and adding DGL, no interaction concern has been identified.

DGL With Antacids

The DGL-plus-antacid combination has specifically been studied (the gastric ulcer trial noted above) and was used effectively. Taking an antacid alongside DGL is well-supported by available evidence.

General Principle

Because DGL does not significantly affect acid secretion, cytochrome P450 enzyme activity, or drug transport proteins at normal doses, drug interactions are considered low risk. That said, anyone on multiple medications for a complex health condition should discuss all supplements with their prescriber.

Money-Back Guarantees on DGL Supplements: What to Read Carefully

A dgl licorice money back guarantee is an increasingly common feature among supplement brands, and it matters — but not all guarantees are created equal. Here is what to look for before you buy.

Why Brands Offer Money-Back Guarantees on Herbal Supplements

The supplement market is crowded, and purchase hesitation is high — particularly among people who have already spent money on products that did not work. A genuine money-back guarantee signals that the brand is confident enough in its product's quality and efficacy to accept the financial risk of dissatisfied customers. It also lowers the barrier to trying a new supplement, which is especially relevant for DGL given that results take 1–4 weeks to become apparent.

What a Legitimate Money-Back Guarantee Should Include

When evaluating any herbal gastritis supplement with a refund policy, look for these specific features:

1. Duration of the guarantee period A 30-day guarantee is the minimum for DGL, given that full clinical benefit may take 4 weeks. A 60 or 90-day guarantee is significantly better, because it gives you enough time to complete a proper trial period before the return window closes. Be skeptical of guarantees shorter than 30 days for any supplement with a 4–8 week recommended use period.

2. Opened or unopened product policy Many supplement refund policies only accept returned product in its original, unopened state — which is obviously useless if you have been taking the supplement for four weeks. A genuine satisfaction guarantee should explicitly cover opened product.

3. Full refund vs. store credit "Money back" should mean actual money returned to your original payment method, not a credit toward future purchases from the same brand.

4. Return shipping cost Who pays return shipping? A consumer-friendly policy covers return shipping or provides a prepaid label. A policy that requires the customer to pay international or tracked shipping fees can cost nearly as much as a small supplement bottle.

5. Quantity limits Many brands limit guarantees to one bottle per household. If you purchased a three-month supply expecting to use all of it, check whether only the first bottle qualifies.

6. Timeframe for refund processing Legitimate brands specify the processing time (commonly 5–14 business days). Absence of this information can be a red flag.

Red Flags to Watch For

• "Satisfaction guaranteed" language with no specific refund mechanism described
• Refunds contingent on proving you used the product correctly
• Guarantees that expire from date of purchase rather than date of delivery
• Third-party marketplace purchases (Amazon, eBay) where the brand's guarantee may not apply — the platform's own policy governs
• Auto-ship/subscription programs that require cancellation before the guarantee can be invoked

Money-Back Guarantees and Trust

It is worth noting that a money-back guarantee, while useful, is one signal among several when evaluating a supplement brand. Pair it with third-party testing certifications, transparent labeling (glycyrrhizin content, extract standardization), organic sourcing where available, and clear customer service contact information. The guarantee is a safety net — the product's quality and transparency should be the primary decision factors.

How to Choose the Best DGL Licorice Drops

If you are ready to try dgl drops for gastritis, here is a structured checklist for evaluating products.

1. Verify Glycyrrhizin Content

The label or product certificate of analysis (COA) should specify glycyrrhizic acid content. Confirmed below 3% meets regulatory standards. Products with documented levels below 1% provide the greatest margin of safety for long-term use.

2. Look for Extract Standardization

The best supplement for gastritis support is one with a standardized extract — meaning the active compounds are measured and consistent batch to batch. Look for a stated DGL extract standardization (e.g., "standardized to X% flavonoids" or "GutGard® extract").

3. Organic Certification

DGL licorice organic sourcing matters for the same reasons it matters in any herb: licorice root can accumulate heavy metals and pesticide residues from the soil. Certified organic production reduces this risk. Third-party heavy metal testing is an additional quality marker.

4. Vegan and Allergen Compatibility

DGL licorice vegan formulations are produced without gelatin capsules or animal-derived excipients. For liquid drops specifically, check for:

• Alcohol-free base (important for those avoiding alcohol for religious, medical, or personal reasons)
• Non-GMO glycerin base (if glycerin is used as the liquid carrier)
• Free from common allergens (gluten, soy, dairy, corn)

5. Bottle Size and Value

A dgl licorice 60ml bottle is the most common liquid format. At standard dosing (3 times daily), calculate whether the bottle provides a minimum 4-week supply to allow for a proper trial before the money-back guarantee window potentially closes.

6. Third-Party Testing

Look for NSF International, USP, Informed Sport, or independent laboratory verification of potency and purity. This is non-negotiable for a supplement you plan to take daily for weeks or months.

7. Manufacturer Transparency

Does the brand publish its COAs? Is there a real customer service phone number or email? Can you find verifiable reviews from people using the product specifically for gastritis or stomach-related issues? Transparent brands have nothing to hide.

Where to Buy DGL Licorice Drops

Knowing dgl licorice where to buy is practical knowledge that affects both the price you pay and the guarantee protection you receive.

Direct From the Brand Website

Best option for guarantee coverage. Purchasing directly from the manufacturer's website ensures that the brand's money-back guarantee applies without ambiguity. You are also more likely to receive authentic product, have access to customer service from the people who made the supplement, and benefit from any subscription discount programs. Most brands ship within 3–5 business days domestically.

Health Food and Natural Supplement Retailers

Stores like Whole Foods Market, Natural Grocers, Sprouts, and independent health food stores typically carry DGL products from established brands. The advantage is immediate availability — no shipping wait. The disadvantage is that store return policies (not the brand's policy) govern refunds, and the selection is limited to brands with retail distribution.

Online Retailers (Amazon, iHerb, Thrive Market)

Broad selection, fast shipping, competitive pricing. However, be aware that:

• The brand's money-back guarantee may not transfer to marketplace purchases
• Third-party marketplace sellers may stock older product
• Amazon's "frequently bought together" suggestions are not clinical recommendations

iHerb is a popular option specifically for supplement shoppers due to its transparent product listings, verified customer reviews, and international shipping capability.

Naturopath and Integrative Medicine Clinics

Practitioners may stock practitioner-grade DGL formulations not available in retail channels, often at higher standardization specifications. If you are working with an integrative practitioner for gastritis management, asking about their preferred DGL product is worthwhile.

What to Avoid

Purchasing from unverified international websites offering suspiciously low prices. The risk of counterfeit, mislabeled, or contaminated supplements is real in the unregulated corners of the supplement market. Stick to established channels with verifiable authentication.

Frequently Asked Questions

Does DGL actually help gastritis, or only reflux and ulcers?

Most of the available clinical research on DGL has focused on peptic ulcers and gastroesophageal reflux rather than on gastritis as a formally diagnosed condition. However, the mechanisms by which DGL provides benefit — mucosal coating, mucus stimulation, mucosal cell regeneration support, anti-inflammatory activity — are directly relevant to gastritis pathophysiology. Extrapolation from ulcer and reflux data is clinically reasonable, and many practitioners specializing in integrative digestive health use DGL specifically for gastritis. The honest answer: the mechanism supports its use, the direct clinical trial data is limited but suggestive.

How long does DGL take to work for stomach inflammation?

Based on the phase III GutGard® trial, symptom improvements can begin as early as day 7, with continued improvement over 28 days. Some people report subjective relief from burning within hours of the first dose, likely due to the direct mucosal-contact effect of liquid formulations.

What is the best dose and timing for DGL drops?

Health Canada's listed range of 380–1,520 mg three times daily provides the regulatory framework. Taking drops 15–20 minutes before meals and at bedtime maximizes mucosal contact during periods of greatest acid exposure. Start at the lower end of the dose range and titrate up over the first week if needed.

Is DGL safe for long-term use?

At doses that keep glycyrrhizic acid below 3% (and ideally below 1%), DGL does not carry the cardiovascular or hormonal risks of whole licorice extract. Long-term daily use at recommended doses is considered safe for most adults without the contraindications listed in the safety section. Periodic reassessment of your gastritis management strategy with a healthcare provider is always advisable.

Can DGL be taken with PPIs, H2 blockers, or antacids?

Yes, without documented pharmacokinetic interaction. DGL's mucosal support mechanism complements rather than duplicates acid-suppression therapy. Many practitioners use DGL alongside pharmaceutical therapy during the acute phase of gastritis treatment.

What is the difference between DGL drops, chewables, and capsules?

Drops offer the fastest mucosal contact and dose flexibility. Chewables have the longest clinical track record and good direct mucosal contact. Capsules are most convenient but deliver the extract only after dissolution in the stomach. See the full comparison section for detail.

Are money-back guarantees real for DGL products, and what are the refund conditions?

Genuine guarantees exist from reputable brands, but the terms vary significantly. Key things to verify: whether opened product is accepted, who pays return shipping, whether you receive a cash refund or store credit, and whether the guarantee period is long enough to complete a proper trial. See the full money-back section.

Is DGL safe if someone has high blood pressure, pregnancy, or is taking other medications?

High blood pressure: DGL at low glycyrrhizin content is generally considered safer than whole licorice, but monitoring is advisable. Pregnancy: Not recommended. Medications: No significant drug interactions documented at therapeutic doses, but discuss with your prescriber if you take multiple medications. Full detail is in the safety section.

Is DGL licorice organic and vegan?

It depends on the brand and formulation. Look specifically for dgl licorice organic certification on the label and confirm dgl licorice vegan compatibility by checking that the liquid carrier and any excipients are free of animal-derived ingredients. The how to choose section covers what to look for.

Final Verdict

If you are living with gastritis and looking for a well-researched, naturally derived option that goes beyond masking symptoms, deglycyrrhizinated licorice drops represent one of the most evidence-informed herbal choices available. The clinical data — including a phase III randomized controlled trial showing benefit by day 7 in 200 participants, multiple ulcer trials showing equivalence to pharmaceutical interventions, and a well-characterized mucosal-support mechanism — places DGL in a meaningfully different category from most herbal supplements.

The liquid drop format specifically offers advantages for gastritis: faster mucosal contact, dose flexibility, and easier administration for people with an inflamed or sensitive upper GI tract. A dgl licorice 60ml bottle at therapeutic dosing gives you the 4–8 week trial period the research supports.

The money-back guarantee element is genuinely important here. Because DGL takes 1–4 weeks to show its full effect, a 30-day minimum (or better, 60–90 day) guarantee with opened-product acceptance is the difference between a risk-free trial and a gamble. Read every term before purchasing.

The key caveats to hold alongside the optimism: the evidence base, while promising, includes a mix of rigorous and uncontrolled trials. DGL is a mucosal support strategy, not an acid suppressor. For H. pylori-associated gastritis, it is an adjunct to — not a replacement for — established eradication therapy. And for people with hypertension, pregnancy, hormone-sensitive conditions, or significant medication regimens, a conversation with a healthcare provider before starting is not just a legal disclaimer — it is genuinely good practice.

Used appropriately, as part of a comprehensive approach that includes dietary adjustment, stress management, identification and management of the root cause of your gastritis, and appropriate medical oversight, dgl licorice gastritis support is a rational, low-risk, and potentially highly beneficial strategy.
