What is H. pylori Botanical Protocol?

The "H. pylori botanical protocol" is not a single traditional formula. It is a modern stack — usually mastic gum, broccoli sprout sulforaphane, berberine, a licorice extract, green tea catechins, black seed, cranberry and one or more probiotic strains — that has grown up in integrative clinics and online forums around a genuinely difficult clinical problem: Helicobacter pylori is common, increasingly antibiotic-resistant, and standard triple or quadruple therapy is unpleasant enough that many people look for something gentler.

Each ingredient was chosen because it has shown some anti-Helicobacter activity in the laboratory, and several have been tested in people. Probiotics given alongside antibiotics have been studied repeatedly and reduce side effects. Berberine-containing quadruple regimens have been compared against standard regimens in Chinese trials with broadly similar eradication rates. Mastic gum, sulforaphane and cranberry have small human studies that mostly show reduced bacterial load or urease activity rather than clearance.

What does not exist is a trial of the whole stack, and no botanical here has been shown to reliably eradicate the infection. H. pylori is classified by the IARC as a group 1 carcinogen because of its link to gastric cancer and MALT lymphoma. That makes this a support page, not an alternative: confirmed infection should be diagnosed, treated and then re-tested by a doctor.

How does H. pylori Botanical Protocol work?

Several different mechanisms are stacked rather than one. Mastic gum resin and its triterpenic acids damage the bacterial cell surface in vitro. Sulforaphane from broccoli sprouts is concentrated in gastric tissue and inhibits H. pylori partly by inducing the host's own NRF2 antioxidant defences in the mucosa. Berberine is a broad antibacterial alkaloid that also appears to inhibit bacterial efflux pumps, which is the rationale for pairing it with antibiotics. Cranberry proanthocyanidins interfere with the adhesion step by which the organism attaches to gastric epithelium. Green tea catechins and Nigella sativa thymoquinone show direct inhibition in culture. Licorice flavonoids and zinc-carnosine act on the host side, supporting mucus and mucosal repair rather than killing bacteria. Probiotics compete for adhesion sites, produce antibacterial metabolites, and — most reliably in human trials — stabilise the gut flora disrupted by antibiotics.

What forms does H. pylori Botanical Protocol come in?

Mastic gum is sold as raw resin tears (chewed, traditional) or as encapsulated powder; capsules are what most trials used. Sulforaphane is best obtained from fresh broccoli sprouts or from a powder that supplies both glucoraphanin and active myrosinase, since glucoraphanin alone converts erratically. Berberine is almost always berberine hydrochloride capsules. Licorice should be deglycyrrhizinated (DGL) or a low-glycyrrhizin standardised extract — full-strength licorice is the main pseudoaldosteronism risk in this stack. Green tea taken as a beverage is far safer than concentrated EGCG capsules, which carry liver signals. Probiotics should be strain-specified with a stated CFU count and an expiry-dated potency, not a "blend" with no strain names.

Where it comes from:

There is no shared traditional lineage here. Chios mastic has been chewed for stomach complaints in the eastern Mediterranean for well over two thousand years and is mentioned by Dioscorides. Licorice is central to both Kampo and Traditional Chinese Medicine for epigastric discomfort. Berberine-containing plants — Coptis in China, Berberis in Ayurveda — were long used for dysentery and gut infection. Black seed has a deep Unani and prophetic-medicine record for digestive complaints. None of these traditions knew of Helicobacter pylori, which was only identified as the cause of most peptic ulcer disease by Marshall and Warren in 1982. The protocol is therefore a modern reverse-engineering: old stomach herbs selected retrospectively because laboratory screening found activity against a newly identified organism.

What does H. pylori Botanical Protocol help with?

• Adjunct support during prescribed H. pylori eradication therapy: This is the best-supported use. Multiple randomised trials and meta-analyses have added probiotics to standard triple or quadruple therapy and found modest improvements in eradication rates alongside clearer reductions in side effects. Separate Chinese trials of berberine-containing quadruple regimens report eradication rates broadly comparable to bismuth quadruple therapy. Importantly, in every one of these studies the botanicals were added to antibiotics, not substituted for them. There is no trial of the full multi-herb stack, and no reason to expect that combining them multiplies the benefit.
• Antibiotic-associated diarrhoea and nausea during treatment: Eradication regimens cause diarrhoea, metallic taste, nausea and bloating in a large minority of people, and side effects are a common reason courses are abandoned. Co-administered probiotics — particularly Saccharomyces boulardii and specific Lactobacillus strains — have been shown across several meta-analyses to reduce the rate of antibiotic-associated diarrhoea and improve completion of therapy. This is a real, replicated benefit and is arguably the strongest reason to use anything from this protocol. Effect sizes are moderate, not dramatic, and strain and dose matter.
• Chronic gastritis symptoms: Small human studies of broccoli sprouts in H. pylori-positive people have reported reduced urease activity and reduced markers of gastric inflammation during the intervention, with values drifting back after sprouts were stopped. Licorice extracts and zinc-carnosine have separate small trials in gastritis showing symptom improvement and better endoscopic appearance. What this means practically is that inflammation and symptoms may ease while the underlying infection persists — which is exactly why symptom improvement should never be read as clearance.
• Functional dyspepsia and epigastric burning: Several of these ingredients have dyspepsia data independent of H. pylori. Mastic gum improved symptom scores versus placebo in a small trial of functional dyspepsia. Licorice extracts and curcumin have also been studied for epigastric discomfort with modest positive results. If your dyspepsia is not caused by H. pylori at all — and much of it is not — these may still help, but persistent upper abdominal pain deserves a diagnosis first, especially over the age of 50 or with any weight loss.
• Peptic ulcer symptom relief and mucosal repair (alongside medical care): Zinc-carnosine and licorice-derived preparations have a long pharmaceutical history in ulcer care, with zinc-carnosine used as a prescription mucosal protectant in Japan and supported by small controlled trials. These act on the stomach lining rather than the bacterium. Active or bleeding ulcers are a medical problem: they need endoscopy, acid suppression and eradication of H. pylori where present. Botanicals belong at the recovery and symptom-management stage, not as first-line treatment.
• Reducing bacterial load when treatment is delayed or declined: Some people cannot tolerate antibiotics, have multiple allergies, or are waiting on a specialist. Small studies of mastic gum, cranberry juice and sulforaphane have shown reductions in bacterial load or urease activity, and one mastic study reported clearance in a small minority of participants. This is a holding measure with a low probability of clearing the infection. It does not remove the long-term gastric cancer risk associated with untreated H. pylori, and the plan should still be to get properly treated and re-tested.
• Repeat or resistant infection after failed eradication: After one or two failed courses, guidelines direct towards susceptibility testing and tailored regimens — not towards herbs. The evidence-based role of botanicals here is narrow: berberine has been studied as a component of rescue-style quadruple regimens, and probiotics may improve tolerability of second-line therapy, which often uses less pleasant drugs. Using a botanical protocol alone after a failed course risks another year of untreated inflammation. Ask about culture or molecular resistance testing.
• Post-treatment gut flora recovery: Eradication therapy is a heavy antibiotic load and measurably disturbs the gut microbiome for weeks to months. Continuing a probiotic after the antibiotics finish is low-risk and is supported by general antibiotic-recovery data, though studies specifically on post-eradication microbiome restoration are small and use varied strains. Fermented foods and fibre do at least as much. This is a sensible, modest use with little downside for people with a normal immune system.

What can H. pylori Botanical Protocol help prevent?

• Antibiotic-associated diarrhoea during eradication therapy: the best-evidenced preventive use in this protocol, supported by multiple probiotic meta-analyses
• Treatment dropout: by improving tolerability, probiotic co-therapy modestly increases the chance a full antibiotic course is completed, which is itself the main driver of successful eradication
• Not established: prevention of initial infection, prevention of reinfection after successful eradication, or prevention of gastric cancer — none of these has adequate human evidence for any botanical here

What are the side effects of H. pylori Botanical Protocol?

• Nausea, bloating, loose stools or constipation: common with berberine and with several extracts at once
• Berberine: cramping, diarrhoea, and a real risk of raising blood levels of other medicines through CYP3A4 and P-glycoprotein inhibition
• Licorice (glycyrrhizin-containing): low potassium, raised blood pressure, fluid retention and ankle swelling — the risk rises with dose, duration and with diuretics; use DGL to avoid this
• Green tea extract: rare but documented idiosyncratic liver injury with concentrated high-dose EGCG capsules — stop immediately with dark urine, pale stools, jaundice or right-sided upper abdominal pain
• Mastic gum: allergic reactions in people sensitive to Pistacia, cashew, pistachio or mango family plants
• Broccoli sprouts: gas and bloating; raw sprouts carry a genuine food-safety risk for pregnant, elderly or immunocompromised people
• Probiotics: transient gas and bloating; rare bloodstream infections in the severely immunocompromised or those with central venous lines
• Curcumin and garlic-containing formulas: increased bruising or bleeding risk with anticoagulants
• Masking of symptoms while an untreated infection continues to damage the gastric lining

Good to know:

The individual ingredients are mostly well tolerated at ordinary doses, but stacking six or eight extracts at once multiplies both the gastrointestinal load and the interaction surface — and it makes it impossible to tell which item caused a problem. Introduce one at a time. The most serious risk associated with this page is not toxicity; it is using botanicals in place of eradication therapy for an infection linked to gastric cancer.

How much H. pylori Botanical Protocol should you take?

• Recommended daily: Doses below reflect what has typically been used in studies of the individual ingredients — there is no validated dose for the stack as a whole, and taking every item at once is neither necessary nor tested. Mastic gum: 350 mg three times daily, or 1 g/day, of encapsulated Chios resin. Broccoli sprouts: roughly 70 g/day fresh sprouts, or a powder supplying about 20–30 mg sulforaphane. Berberine HCl: 500 mg two to three times daily — this is the ingredient most likely to interact with prescription medicines. DGL licorice: 380–760 mg chewed before meals. Green tea: 2–3 cups daily is preferable to high-dose EGCG capsules. Probiotics: 10–20 billion CFU/day of a named strain such as Saccharomyces boulardii CNCM I-745 or Lacticaseibacillus reuteri DSM 17938. Zinc-carnosine: 75–150 mg/day. Cranberry: about 250 ml/day of unsweetened juice or an equivalent standardised PAC extract.
• Best time of day: Mastic gum and DGL are usually taken before meals. Berberine is taken with meals to blunt gastrointestinal upset and because of its effect on post-meal glucose. Probiotics during antibiotic therapy are best spaced 2–3 hours away from each antibiotic dose. Broccoli sprouts can be eaten at any meal.
• With or without food: Berberine, zinc-carnosine and green tea extracts should be taken with food — green tea extract on an empty stomach is associated with more liver-related reports. Mastic gum and DGL are conventionally taken 20–30 minutes before eating.
• Time to effect: Symptom changes are often noticed in 2–4 weeks. Any change in infection status cannot be judged by how you feel; it requires a urea breath test or stool antigen test done at least 4 weeks after antibiotics and 2 weeks after stopping PPIs, or the result will be falsely negative.
• How long to take it: Most component studies ran 2–12 weeks. Use the protocol as a defined course tied to your treatment plan rather than indefinitely: berberine, high-dose green tea extract and any glycyrrhizin-containing licorice are not intended for open-ended daily use. If you are H. pylori positive, the endpoint is a negative confirmatory test after proper eradication therapy — not a subjective sense of improvement.
