## Overview

Kachnar (Bauhinia variegata) is an Ayurvedic herb containing flavonoids, phenolic compounds, and saponins that demonstrate antioxidant and [hepatoprotective](/ingredients/condition/detox) activities. The bioactive compounds work primarily through [free radical scaveng](/ingredients/condition/antioxidant)ing mechanisms and modulation of liver detoxification enzymes.

## Health Benefits

• Antioxidant activity demonstrated through in vitro [free radical scaveng](/ingredients/condition/antioxidant)ing of DPPH, superoxide, nitric oxide, and hydrogen peroxide (P ≥ 0.001) - preclinical evidence only
• [Hepatoprotective](/ingredients/condition/detox) effects shown in carbon tetrachloride-intoxicated rats (PMID: 17827931) - animal studies only
• [Anti-inflammatory](/ingredients/condition/inflammation) properties attributed to terpenoid and steroid content - traditional use with preclinical support
• Potential antidiabetic activity based on traditional use and preliminary laboratory studies - no human trials
• Antimicrobial and [immunomodulatory](/ingredients/condition/immune-support) effects observed in vitro - requires human validation

## Mechanism of Action

Kachnar's flavonoids and phenolic compounds neutralize DPPH, superoxide, nitric oxide, and hydrogen peroxide radicals through electron donation mechanisms. The herb's saponins appear to enhance hepatic [glutathione](/ingredients/condition/detox) levels and support cytochrome P450 enzyme function. These compounds may also inhibit [pro-inflammatory cytokine](/ingredients/condition/inflammation) production through NF-κB pathway modulation.

## Clinical Summary

Current evidence for Kachnar is limited to preclinical studies with no human clinical trials available. In vitro studies demonstrate significant [free radical scaveng](/ingredients/condition/antioxidant)ing activity (P ≥ 0.001) against multiple oxidative species. Animal studies in carbon tetrachloride-intoxicated rats showed [hepatoprotective](/ingredients/condition/detox) effects, though sample sizes and specific outcome measures require further documentation. The lack of human studies significantly limits clinical applicability and dosage recommendations.

## Nutritional Profile

**Macronutrients (per 100 g fresh flower buds, approximate):** Moisture: 78–82 g; Protein: 3.5–4.2 g; Total fat: 0.6–0.9 g; Crude fiber: 2.8–3.5 g; Carbohydrates (by difference): 10–14 g; Energy: ~60–70 kcal. **Macronutrients (per 100 g dried stem bark):** Protein: 5–7 g; Crude fiber: 18–24 g; Ash: 6–9 g. **Minerals (flower buds, per 100 g fresh weight):** Calcium: 60–90 mg; Phosphorus: 40–55 mg; Iron: 2.0–3.8 mg; Magnesium: 30–50 mg; Potassium: 180–260 mg; Zinc: 0.8–1.5 mg; Manganese: 0.4–0.9 mg; Copper: 0.2–0.5 mg. **Vitamins:** Ascorbic acid (vitamin C): 9–15 mg/100 g fresh buds; β-carotene (provitamin A): trace–0.3 mg/100 g; small amounts of B-complex vitamins (thiamine, riboflavin, niacin — individually <0.5 mg/100 g). **Key Bioactive Compounds:** (1) **Flavonoids** — Quercetin (0.12–0.45% w/w in dried bark), kaempferol, rutin, and myricetin glycosides; quercetin-3-O-glucoside and kaempferol-3-O-rutinoside identified in flowers. (2) **Phenolic acids** — Gallic acid (0.08–0.25% w/w dried bark), ellagic acid, caffeic acid, protocatechuic acid. (3) **Tannins** — Total tannin content in bark: 8–18% w/w (predominantly condensed tannins/proanthocyanidins). (4) **Terpenoids & sterols** — β-Sitosterol (0.03–0.08% w/w bark), lupeol (0.02–0.06%), β-amyrin, stigmasterol; ursolic acid and oleanolic acid reported in leaves. (5) **Bauhiniastatins** — Novel dibenz[b,f]oxepins (bauhiniastatin-1 through -4), isolated from stem bark at trace levels (~0.001–0.01% w/w); these are considered chemotaxonomic markers. (6) **Lectins** — Bauhinia variegata lectin (BVL), a galactose-specific lectin found in seeds at ~1–3 mg/g seed weight; shows hemagglutinating activity. (7) **Other compounds** — Bauhinione (a bioflavonoid-type ketone in heartwood), β-sitosterol-β-D-glucoside, and hentriacontane in bark wax. **Total phenolic content (bark extract):** 85–150 mg gallic acid equivalents (GAE)/g dry extract. **Total flavonoid content (bark extract):** 40–80 mg quercetin equivalents (QE)/g dry extract. **Bioavailability Notes:** Quercetin and kaempferol glycosides undergo hydrolysis by intestinal β-glucosidases before absorption; oral bioavailability of free quercetin is estimated at only 2–5% in humans, though glycoside forms (especially glucosides) are better absorbed than aglycones. High tannin content (8–18%) may reduce protein and mineral (iron, zinc) bioavailability through chelation — relevant when bark is consumed as decoction. Lupeol and β-sitosterol are lipophilic with low oral bioavailability (~5–10%); co-administration with dietary fat or oil-based formulations may enhance absorption. The lectin BVL is a protein and is largely degraded during cooking or gastric [digestion](/ingredients/condition/gut-health), limiting systemic activity when consumed orally. Ascorbic acid in fresh buds enhances non-heme iron absorption when consumed together. Traditional Ayurvedic preparations (kvatha/decoction) primarily extract water-soluble phenolics and tannins, while churna (powder) formulations retain lipophilic terpenoids and sterols.

## Dosage & Preparation

No clinically studied dosage ranges are available due to the complete absence of human trials. Preclinical studies used ethanolic or aqueous extracts of stem bark, but human-equivalent doses have not been established. Consult a healthcare provider before starting any new supplement.

## Safety & Drug Interactions

Safety data for Kachnar is extremely limited with no established side effect profile or drug interaction studies. Traditional Ayurvedic use suggests general tolerability, but modern safety parameters remain undefined. Potential interactions with hepatic [metabolism](/ingredients/condition/weight-management) drugs are theoretically possible given the herb's effects on liver enzymes. Pregnant and breastfeeding women should avoid use due to insufficient safety data, and individuals with liver conditions should consult healthcare providers before use.

## Scientific Research

No human clinical trials, randomized controlled trials, or meta-analyses have been conducted on Kachnar. All available evidence is limited to preclinical in vitro and animal studies, such as the [hepatoprotective](/ingredients/condition/detox) study in Sprague-Dawley rats (PMID: 17827931).

## Historical & Cultural Context

In Ayurveda and Indian traditional medicine, Kachnar stem bark has been used for centuries as an alternative, tonic, and astringent, particularly the red-flowered variety for treating ulcers. Traditional applications span the sub-Himalayan and Indian systems, with various plant parts used for wounds, [inflammation](/ingredients/condition/inflammation), and metabolic disorders.
