Introduction
Helicobacter pylori infection is a major global health concern, affecting nearly one-third of the world’s population and playing a central role in the pathogenesis of chronic gastritis, peptic ulcer disease, and gastric malignancy.1 Conventional eradication regimens, including triple and Bismuth-based therapies, though effective, are increasingly challenged by antibiotic resistance, recurrence, and gastrointestinal adverse effects. This has led to growing interest in complementary and alternative therapeutic strategies. In Ayurveda, gastric disorders associated with ulceration and dyspeptic symptoms are addressed through a wide range of plant-based formulations that possess antimicrobial, gastroprotective, anti-inflammatory, and antioxidant properties. Many of these botanicals have demonstrated significant anti-H. pylori activity in preclinical and in vitro studies, suggesting their potential role as adjuncts or alternatives in infection management.
Ayurvedic botanicals with anti-H. pylori activity
Haridra (Curcuma longa):
Turmeric, particularly its active constituent curcumin, has been widely used in Ayurveda for its antiseptic and anti-inflammatory properties. Curcumin has been shown to inhibit the growth of CagA-positive H. pylori strains in vitro. It has also been observed that NF-κB activation is suppressed by curcumin, thereby reducing inflammatory responses in infected gastric epithelial cells. Methanolic extracts of Curcuma longa have demonstrated broad-spectrum inhibitory activity against multiple H. pylori strains.
Ginger (Zingiber officinale):
Ginger has long been used in traditional medicine for gastrointestinal protection. Gingerols, the key bioactive phenolic compounds, exhibit strong inhibitory effects against H. pylori, including CagA-positive strains. Additionally, ginger extracts have been shown to inhibit proton-potassium ATPase activity, thereby reducing gastric acidity and limiting bacterial colonization.
Twak (Cinnamomum spp.):
Cinnamon extracts demonstrate dual anti-H. pylori effects. Methylene chloride extracts inhibit bacterial growth, while ethanol extracts suppress urease activity, an essential virulence factor of H. pylori. These findings highlight cinnamon’s role in disrupting bacterial survival mechanisms.
Amragandhi Haridra:
Phenolic fractions of mango ginger have been reported to inhibit both proton-potassium ATPase activity and H. pylori growth, supporting its gastroprotective and anti-secretory potential.
Kalajaji:
Black seed has shown clinically relevant anti-H. pylori activity. Eradication rates approaching those of standard triple therapy have been reported, indicating its potential as a cost-effective alternative or adjunct treatment.
Sharpunkha (Tephrosia purpurea) and Kampillaka (Mallotus philippinensis):
Apolar fractions of Tephrosia purpurea exhibit activity against both standard and antibiotic-resistant H. pylori strains. Similarly, ethanolic extracts of Mallotus philippinensis and its compound rottlerin show strong bactericidal effects, including activity against Clarithromycin- and Metronidazole-resistant strains.
Chitraka (Plumbago zeylanica):
Various extracts of Plumbago zeylanica demonstrate significant anti-H. pylori activity, confirming its traditional use in digestive disorders.
Black Myrobalan (Terminalia chebula):
Aqueous extracts of haritaki exhibit strong antibacterial activity against H. pylori, with notable minimum inhibitory and bactericidal concentrations, supporting its role in gastric protection.
Garlic (Allium sativum):
Garlic extract has been shown to inhibit H. pylori growth and reduce infection-induced gastritis, thereby potentially lowering the risk of gastric carcinoma.
Resveratrol and tea polyphenols
Polyphenols such as Resveratrol and catechins from green and black tea exhibit strong anti-H. pylori activity. These compounds exert antioxidant effects while also inhibiting bacterial growth and adhesion to gastric mucosa.
Mechanisms of action
Ayurvedic botanicals exert anti-H. pylori effects through multiple mechanisms. These include direct bactericidal activity, inhibition of urease enzyme, suppression of bacterial adhesion, and modulation of host inflammatory pathways. Additionally, antioxidant phytochemicals such as flavonoids and polyphenols neutralize reactive oxygen species, reduce gastric mucosal damage, inhibit pepsin and acid secretion, and promote mucosal regeneration. Collectively, these actions help restore gastric integrity and reduce ulcer formation.
Conclusion
An Ayurvedic approach to Helicobacter pylori infection offers a promising complementary strategy rooted in the therapeutic potential of medicinal plants. Herbs such as turmeric, ginger, black seed, cinnamon, haritaki, and garlic demonstrate significant anti-H. pylori activity along with gastroprotective and anti-inflammatory effects. Although most evidence is derived from in vitro and animal studies, the findings suggest meaningful therapeutic potential. Further well-designed clinical trials are needed to validate efficacy, establish standardized dosing, and integrate these botanicals into evidence-based management protocols for H. pylori-associated gastrointestinal disorders.2
