# Poondu (Allium sativum) **Canonical URL:** https://ingredients.hermeticasuperfoods.com/ingredients/poondu **Data Source:** Hermetica Superfoods Ingredient Encyclopedia **Updated:** 2026-03-19 **Evidence Score:** 8 / 10 **Category:** Southeast Asian **Also Known As:** Allium sativum, garlic, lahsun, dasuan, ajo, aglio, vellulli, thoom ## Overview Poondu (Allium sativum) is garlic used in Siddha medicine, containing organosulfur compounds like allicin that exhibit [antimicrobial](/ingredients/condition/immune-support) and [cardiovascular](/ingredients/condition/heart-health) effects. These bioactive compounds modulate sulfur [metabolism](/ingredients/condition/weight-management) and nitric oxide pathways in vascular tissue. ## Health Benefits • No clinical health benefits can be cited as the research dossier contains no human clinical trials, RCTs, or meta-analyses with specific health outcomes • Traditional medicine applications are referenced but without specific indications or evidence quality • The presence of organosulfur compounds (allicin, alliin, diallyl sulfides) suggests potential bioactivity but lacks clinical validation in this research • No evidence-based health claims can be made from the provided research dossier • Further clinical research is needed to establish specific health benefits ## Mechanism of Action Poondu's organosulfur compounds, primarily allicin and ajoene, inhibit HMG-CoA reductase enzyme affecting cholesterol synthesis. These compounds also stimulate endothelial nitric oxide synthase (eNOS) promoting vasodilation. Additionally, allicin demonstrates [antimicrobial](/ingredients/condition/immune-support) activity by disrupting bacterial cell membrane integrity through sulfhydryl group interactions. ## Clinical Summary Current research dossier contains no human clinical trials, randomized controlled trials, or meta-analyses evaluating poondu's health outcomes. Traditional Siddha medicine applications are documented but lack quantified therapeutic endpoints or standardized preparations. Evidence base relies primarily on in-vitro studies of organosulfur compounds rather than clinical validation. Further human studies are needed to establish therapeutic efficacy and optimal dosing protocols. ## Nutritional Profile Poondu (Allium sativum/Garlic) per 100g raw: Calories: ~149 kcal; Macronutrients: Carbohydrates 33.1g (primarily fructooligosaccharides and inulin acting as [prebiotic](/ingredients/condition/gut-health)s), Protein 6.4g (containing all essential amino acids in modest amounts), Fat 0.5g, Dietary Fiber 2.1g, Water 58.6g; Micronutrients: Vitamin C 31.2mg (35% DV), Vitamin B6 (pyridoxine) 1.24mg (72% DV), Thiamine (B1) 0.2mg, Riboflavin (B2) 0.11mg, Folate 3mcg, Vitamin K 1.7mcg; Minerals: Manganese 1.67mg (72% DV), Selenium 14.2mcg (21% DV), Phosphorus 153mg (15% DV), Calcium 181mg (14% DV), Potassium 401mg (9% DV), Iron 1.7mg (9% DV), Copper 0.3mg, Zinc 1.16mg, Magnesium 25mg; Bioactive Organosulfur Compounds: Alliin (precursor) ~10-30mg/g dry weight, Allicin (formed enzymatically upon crushing/cutting via alliinase activity) ~2.5-4.5mg/g fresh weight with rapid degradation within hours of formation, Diallyl disulfide (DADS) and Diallyl trisulfide (DATS) formed during cooking/processing, S-allylcysteine (SAC) ~0.5-1.6mg/g in aged garlic extract with higher stability than allicin, S-allylmercaptocysteine (SAMC); Other Bioactives: Quercetin ~47mg/100g (flavonoid), Kaempferol trace amounts, Fructans (inulin-type) ~9-16g/100g dry weight serving as prebiotic substrate; Bioavailability Notes: Allicin is highly unstable and largely destroyed by heat, acid (stomach pH), and prolonged cooking — raw crushing and immediate consumption maximizes allicin yield; SAC in aged garlic extract demonstrates superior oral bioavailability (~98% absorption) compared to raw allicin; fat-soluble sulfur compounds (DADS, DATS) have enhanced absorption with dietary fats; Vitamin C content reduced approximately 30-60% upon cooking; typical culinary serving size in Southeast Asian cuisine is 3-10g per dish, delivering proportionally scaled micronutrient contributions ## Dosage & Preparation No clinically studied dosage ranges for extracts, powder, or standardized forms are specified in the research results. Standardization details are not available. Consult a healthcare provider before starting any new supplement. ## Safety & Drug Interactions Poondu may increase bleeding risk when combined with anticoagulant medications due to antiplatelet effects of organosulfur compounds. Gastrointestinal irritation, heartburn, and allergic reactions can occur, particularly with raw preparations. May interact with diabetes medications by potentiating hypoglycemic effects. Pregnancy and breastfeeding safety requires medical supervision due to limited safety data in these populations. ## Scientific Research The research dossier explicitly states that search results lack specific human clinical trials, RCTs, or meta-analyses with PubMed PMIDs. No studies on clinical outcomes, sample sizes, or designs are detailed in the available research. ## Historical & Cultural Context Garlic (Allium sativum) has been used in global traditional medicine systems for its therapeutic properties. The research references general traditional uses but does not detail specific systems, indications, or historical duration of use. ## Synergistic Combinations Insufficient research data to determine synergistic combinations ## Frequently Asked Questions ### What is the active compound in poondu? The primary active compound in poondu is allicin, an organosulfur compound formed when garlic is crushed or chopped. Other bioactive organosulfur compounds include ajoene and diallyl sulfides, which contribute to its traditional medicinal properties. ### How is poondu used in Siddha medicine? In Siddha medicine, poondu is traditionally used for cardiovascular and digestive conditions, though specific therapeutic protocols vary. It may be prepared as fresh juice, paste, or incorporated into polyherbal formulations according to classical Siddha texts. ### Can poondu interact with blood thinners? Yes, poondu can potentially interact with blood-thinning medications like warfarin due to its antiplatelet effects from organosulfur compounds. This interaction may increase bleeding risk and requires medical monitoring if used concurrently. ### What's the difference between poondu and regular garlic? Poondu refers specifically to garlic (Allium sativum) as used in traditional Siddha medicine system. While botanically identical to regular garlic, poondu emphasizes traditional preparation methods and therapeutic applications within Siddha medical framework. ### Are there clinical studies on poondu's health benefits? Currently, there are no specific clinical trials evaluating poondu's health outcomes in human subjects. While traditional applications are documented, evidence-based validation through randomized controlled trials remains lacking for this specific Siddha medicine preparation. ### Is poondu safe to take during pregnancy and breastfeeding? While poondu (garlic) is commonly used in traditional cooking and Siddha medicine, specific safety data for pregnancy and breastfeeding is limited. Pregnant and breastfeeding women should consult a healthcare provider before using poondu supplements, as concentrated forms may differ from culinary amounts. Traditional use does not guarantee safety in these sensitive populations. ### What is the recommended dosage of poondu for daily use? Standardized dosage guidelines for poondu supplements are not established due to limited clinical research. Traditional Siddha medicine practitioners typically recommend dosages based on individual constitution and condition, but these lack rigorous clinical validation. Anyone considering poondu supplementation should consult a qualified practitioner familiar with Siddha medicine for personalized dosing. ### How does the bioavailability of poondu change when it is cooked versus raw? Heat can affect organosulfur compounds like allicin in poondu, potentially altering its bioactive profile, though specific comparative bioavailability data for poondu is not available in clinical literature. Raw poondu retains more intact alliin and other volatile compounds, while cooking may reduce some but increase other beneficial sulfur derivatives. The optimal form for therapeutic use remains unclear without human bioavailability studies. --- *Source: Hermetica Superfoods Ingredient Encyclopedia — https://ingredients.hermeticasuperfoods.com* *License: CC BY-NC-SA 4.0 — Attribution required.
