# Vaijayanti (Holarrhena antidysenterica) **Canonical URL:** https://ingredients.hermeticasuperfoods.com/ingredients/vaijayanti **Data Source:** Hermetica Superfoods Ingredient Encyclopedia **Updated:** 2026-03-20 **Evidence Score:** 2 / 10 **Category:** Ayurveda **Also Known As:** Holarrhena antidysenterica, Kurchi, Kutaja, Indrajav, Tellicherry bark, Conesse bark, Kalinga, Kureya ## Overview Holarrhena antidysenterica is an Ayurvedic medicinal tree whose bark contains alkaloids like conessine that demonstrate calcium channel blocking activity. The bark preparations have been traditionally used for gastrointestinal disorders, particularly diarrhea and dysentery. ## Health Benefits • Gastrointestinal support through calcium channel blocking and histamine receptor activation (mechanism studies only) • Traditional antidiarrheal effects from bark preparations (ethnopharmacological documentation) • Potential antidiabetic properties from seed extracts (traditional use only) • Antiparasitic/anthelmintic activity against intestinal worms (traditional application) • Possible [inflammatory](/ingredients/condition/inflammation) bowel disease support including colitis and Crohn's disease (traditional use basis) ## Mechanism of Action The primary alkaloid conessine blocks L-type calcium channels and modulates histamine H3 receptors, affecting smooth muscle contraction in the gastrointestinal tract. These mechanisms may contribute to antispasmodic effects and reduced intestinal motility. The bark also contains other steroidal alkaloids that may influence cholinergic pathways. ## Clinical Summary Current evidence is limited to mechanism studies and ethnopharmacological documentation rather than controlled human trials. Laboratory studies have confirmed calcium channel blocking activity of isolated alkaloids, but therapeutic efficacy in humans remains unproven. Traditional use documentation supports antidiarrheal applications, though standardized clinical data is lacking. Most research focuses on compound identification rather than clinical outcomes. ## Nutritional Profile Holarrhena antidysenterica (Vaijayanti) is a medicinal plant, not a dietary staple, so conventional macronutrient profiling is limited; however, bioactive compound characterization is reasonably documented. Primary bioactive constituents are steroidal alkaloids concentrated in bark and seeds: conessine (major alkaloid, ~1.5–3.2% dry weight in bark), kurchicine, holarrhimine, holarrhesine, conarrhimine, and holarrhine. Seeds contain approximately 20–25% fixed oils (fatty acid profile includes oleic, linoleic, and palmitic acids). Bark contains tannins (~8–12% dry weight) contributing to astringent antidiarrheal properties. Flavonoids including quercetin and kaempferol derivatives are present at trace levels (~0.1–0.4% dry weight). Phytosterols (beta-sitosterol, stigmasterol) detected in leaf and bark fractions. Crude fiber content in bark preparations is approximately 15–18% dry weight. Protein content in seeds estimated at 12–18% dry weight with limited bioavailability data. Saponins present at ~2–4% in root bark. Mineral content includes calcium (~180–220 mg/100g dry bark), potassium (~310 mg/100g), magnesium (~85 mg/100g), and iron (~12–15 mg/100g), though these values are derived from proximate analyses of dried bark powder. Vitamin content is not well characterized; trace amounts of tocopherols reported in seed oil fractions. Bioavailability of alkaloids such as conessine is moderate via oral route; tannins may reduce mineral absorption when consumed in therapeutic bark decoctions. Preparations are typically used at low doses (3–6g bark powder or 50–100mL decoction), so macronutrient contribution to diet is negligible. ## Dosage & Preparation No clinically studied dosage ranges are available in the current research. Traditional preparations use bark, leaves, or seeds, but standardization parameters and recommended doses have not been established through clinical trials. Consult a healthcare provider before starting any new supplement. ## Safety & Drug Interactions Safety data is insufficient for modern supplement use, with traditional preparations potentially containing variable alkaloid concentrations. The calcium channel blocking activity may interact with [cardiovascular](/ingredients/condition/heart-health) medications or calcium channel blockers. Alkaloid-containing preparations should be avoided during pregnancy and breastfeeding due to unknown teratogenic potential. Gastrointestinal side effects or alkaloid toxicity could occur with excessive use. ## Scientific Research The available research consists primarily of phytochemical characterization studies and ethnopharmacological reviews rather than clinical trials. No human clinical trials, randomized controlled trials, or meta-analyses with specific PMIDs were found in the research dossier. ## Historical & Cultural Context Known as Tewāj, Amkudu (Telugu), Erukkalaipalai (Tamil), or Conesse/Tellicherry bark in English, this plant has been used across South Asian traditional medicine systems. Historical applications focused on treating dysentery, parasitic worm infections, and various gastrointestinal conditions. ## Synergistic Combinations Triphala, Kutaja, Bilva, Musta, Chitrak ## Frequently Asked Questions ### What is the active compound in Holarrhena antidysenterica? The primary active alkaloid is conessine, along with other steroidal alkaloids found in the bark. These compounds demonstrate calcium channel blocking activity in laboratory studies. ### How does Holarrhena antidysenterica help with diarrhea? Traditional use suggests antidiarrheal effects, possibly through alkaloid-mediated reduction of intestinal motility and smooth muscle relaxation. However, this mechanism lacks clinical validation in human studies. ### Is Holarrhena antidysenterica safe to take daily? Safety data for regular supplementation is insufficient, as traditional use typically involved short-term bark preparations. The alkaloid content raises concerns about potential toxicity with chronic use. ### Can Holarrhena antidysenterica interact with blood pressure medications? Theoretical interactions exist due to calcium channel blocking activity of conessine alkaloids. This could potentially enhance the effects of calcium channel blocker medications used for hypertension. ### What part of Holarrhena antidysenterica is used medicinally? The bark is the primary medicinal part used in traditional Ayurvedic preparations, containing the highest concentration of therapeutic alkaloids. Seeds have also been used traditionally but contain different compound profiles. ### Is Holarrhena antidysenterica safe during pregnancy and breastfeeding? Holarrhena antidysenterica has not been adequately studied in pregnant or breastfeeding women, and traditional use does not establish safety in these populations. It is advisable to avoid this supplement during pregnancy and lactation unless explicitly recommended by a qualified healthcare provider. Women planning pregnancy or currently breastfeeding should consult with their healthcare practitioner before use. ### What is the most effective form of Holarrhena antidysenterica—bark, seed, or standardized extract? Traditional preparations primarily use the dried bark, which contains the most documented antidiarrheal alkaloids in ethnopharmacological literature. Seed extracts have been studied for potential antidiabetic properties, though clinical evidence remains limited to traditional use claims. Standardized extracts are not widely available, and efficacy comparisons between forms lack robust clinical data. ### What does current research evidence show about Holarrhena antidysenterica's effectiveness? Most evidence for Holarrhena antidysenterica comes from traditional use documentation and laboratory mechanism studies rather than rigorous clinical trials in humans. While in vitro studies suggest potential calcium channel blocking and antiparasitic activity, these findings have not been reliably confirmed in controlled clinical settings. The strongest evidence base exists for its traditional antidiarrheal use, though modern clinical research on efficacy and safety remains limited. --- *Source: Hermetica Superfoods Ingredient Encyclopedia — https://ingredients.hermeticasuperfoods.com* *License: CC BY-NC-SA 4.0 — Attribution required.
