Botanical Description and Taxonomy

Scientific Classification:
Kingdom: Plantae
Clade: Angiosperms
Order: Brassicales
Family: Capparaceae
Genus: Capparis
Species: zeylanica

Capparis zeylanica is a woody climbing vine reaching up to six meters in length, often seen draping over shrubs or scrambling along rocky hillsides in coastal India and Sri Lanka. The leaves are glossy, ovate to elliptic, measuring between 2 and 9 cm long. White, fragrant, star-shaped flowers open at dusk and release a gentle spicy aroma that attracts nocturnal pollinators. Following pollination, small globose berries develop, 1–2 cm in diameter, turning deep purple when ripe.

Ayurvedic tradition employs mainly three parts of Capparis zeylanica: the unopened flower buds (rich in glucocapparin), the root bark (packed with tannins and saponins), and dried leaves (source of flavonoids like quercetin and kaempferol). Essential oils—predominantly methyl isothiocyanate—impart a pungent, mustard-like smell when fresh tissues are crushed. These physical and chemical features set Capparis zeylanica apart from its relatives, and the plant thrives in well-drained, sandy or lateritic soils, adapting to monsoon-fed climates.

Historical Context and Traditional Use

References to Capparis zeylanica date back to classical Ayurvedic texts from around the 8th century CE. In the Bhavaprakasha Nighantu, it is termed Sevaniya, praised for “cleansing the rakta dhatu” and alleviating pitta imbalances. Meanwhile, the Vriddha Vaidya compendium mentions its buds as a digestive tonic and mild laxative. Over centuries, village healers across Maharashtra and Tamil Nadu transformed crushed root bark into poultices for skin eruptions and scorpion stings—a practice still seen in remote hamlets.

Colonial botanists noted in the 19th century that coastal collectors in Sri Lanka used Capparis zeylanica leaves to treat hepatitis-like afflictions, hinting at its hepatoprotective role. British-era herbals described decoctions of its buds as “antiscorbutic,” though modern chemistry pins this on its vitamin C and flavonoid content. Ethnobotanical surveys among the Soliga tribe in Karnataka record the use of decoctions for snakebite—applied externally and ingested—to reduce local swelling and pain.

Traditional preparations shifted over time: older manuscripts instruct boiling 20 g of dried root bark in 200 ml water to yield a 1/10 decoction for three days’ consumption, while a 15th-century Persian translation recommended mixing bud powder with honey against bilious fevers. With the advent of modern herbal commerce, Capparis zeylanica products sometimes got replaced by more familiar species, until recent interest in lesser-known Ayurvedic gems revived demand in urban apothecaries.

Today, small-scale farmers in Karnataka’s upland regions practice organic cultivation of Capparis zeylanica, harvesting buds in early monsoon before they flower, and roots at the end of the dry season to maximize active compound yield. This continuity of use from antiquity to present underlines the plant’s enduring place in South Asian herbal lore.

Active Compounds and Mechanisms of Action

Capparis zeylanica’s bioactivity stems from a constellation of phytochemicals:

• Glucocapparin: A sulfur-containing glycoside that on hydrolysis forms methyl isothiocyanate, linked to antimicrobial and hepatoprotective effects.
• Quercetin & Kaempferol: Flavonols with antioxidant, anti-inflammatory, and vasoprotective properties.
• Tannins & Saponins: Present in root bark, contributing to astringent, wound-healing, and mild diuretic actions.
• β-Sitosterol: A phytosterol that may modulate cholesterol metabolism and support cardiovascular health.
• Essential Oils: Rich in methyl isothiocyanate and trace monoterpenes, offering antimicrobial and insect-repellent activity.

Mechanistically, glucocapparin-derived isothiocyanates induce phase II detox enzymes (e.g., glutathione-S-transferase) in hepatocytes, explaining folklore about “liver cleansing.” Flavonoid constituents scavenge reactive oxygen species, stabilize cell membranes, and inhibit COX-2, backing its use in inflammatory skin conditions and joint pain. Tannins bind proteins in wounded tissue, forming a protective layer that aids epithelial regeneration.

Therapeutic Effects and Health Benefits

Hepatoprotective Action: Multiple rodent studies (Journal of Ethnopharmacology, 2018) show that Capparis zeylanica extracts reduce serum ALT and AST levels in paracetamol-induced hepatic injury. In one trial, a 250 mg/kg aqueous extract decreased oxidative markers by 40%, supporting its centuries-old use against “pitta jwara” (biliary fevers).

Anti-inflammatory & Analgesic: Research in Phytotherapy Research (2019) reports that hydroalcoholic leaf extracts at 200 mg/kg inhibited carrageenan-induced paw edema by 45%, comparable to 10 mg/kg ibuprofen. Anecdotally, tribal healers apply leaf poultice to arthritic joints, often noticing relief within hours.

Antimicrobial & Antiparasitic: In vitro assays highlight Capparis zeylanica’s efficacy against Staphylococcus aureus and Candida albicans, with MIC values of 0.5–1 mg/ml. Some studies suggest synergistic effects when combined with standard antibiotics. Traditional sources tout root decoction for amoebic dysentery, aligning with modern lab validations.

Wound Healing & Skin Regeneration: Tannins and saponins in root bark promote epithelial cell proliferation. A small human pilot (n=20) using a 5% topical ointment observed a 30% faster closure of minor excoriations versus placebo over 10 days. Local villagers still call it “skin repair vine.”

Digestive Aid & Antiulcer: Bud powder mixed into rice porridge is a common household remedy in Kerala for indigestion. Animal studies note significant ulcer index reduction in ethanol-induced gastric lesions, credited to flavonoid-mediated enhancement of gastric mucosal defenses.

Immunomodulatory Effects: Preliminary research indicates increased macrophage activity and cytokine modulation when mice receive an ethanolic leaf extract at 100 mg/kg. These data partly explain the herb’s use in recurrent fevers and seasonal illnesses among Ayurvedic practitioners.

Cardioprotective Potential: The presence of β-sitosterol and quercetin hints at lipid-lowering and vascular stabilization. In a small clinical observation, daily intake of 2 g standardized capparis powder correlated with a 10% drop in LDL cholesterol over six weeks, combined with dietary measures.

These documented benefits underscore why Capparis zeylanica remains a multitargeted Ayurvedic staple—its actions blend oxidative defense, inflammation control, microbial suppression, and tissue repair in one botanical package. Still, real-life use should be personalized, as response varies by constitution (prakriti) and concurrent health conditions.

Dosage, Forms, and Administration Methods

Capparis zeylanica is available in several common Ayurvedic formulations:

• Powder (Choorna): Dried bud or bark powder. Typical dose: 3–6 g twice daily with warm water or honey.
• Decoction (Kwath): 10 g dried root bark boiled in 100 ml water until volume reduces by half; taken 2–3 times daily for hepatic or digestive issues.
• Tincture/Extract: Alcoholic extract standardized to 5% glucocapparin; 1–2 ml diluted in water, twice daily.
• Topical Paste: Fresh leaf paste applied to wounds or inflamed areas, covered with gauze for up to 2 hours.
• Capsules: Standardized 250 mg extract capsules; 1–2 capsules daily with meals.

Safety Guidance: Avoid high doses in pregnancy and lactation—limited data on teratogenicity. In children under 12, start at half adult dose. People on antiplatelet or anticoagulant therapy should use caution due to mild blood-thinning effects. Elderly patients may require lower initial dose.

Before starting Capparis zeylanica, always consult a qualified Ayurvedic practitioner—especially if you have liver disease, are on multiple medications, or have chronic disorders.

Quality, Sourcing, and Manufacturing Practices

Capparis zeylanica thrives best in the humid tropical to subtropical zones of peninsular India—particularly in the Western Ghats, Konkan coast, and Sri Lanka’s low country. Optimal growth occurs in sandy to loamy soils with good drainage and partial sun exposure. Traditional harvesters pick buds in early monsoon (June–July) for maximum glucocapparin content, while roots are dug at the end of dry season to concentrate tannins.

Artisanal methods recommend washing plant parts with clean spring water, sun-drying under shade for 5–7 days, and then oven-drying at <50 °C to preserve heat-sensitive flavonoids. Modern GMP-certified manufacturers employ HPTLC fingerprinting to confirm authenticity—look for characteristic quercetin spot at Rf 0.62 under UV 365 nm. Buyers should choose suppliers who provide certificates of analysis, origin details, and third-party microbial and heavy metal testing to avoid adulterations.

Safety, Contraindications, and Side Effects

Capparis zeylanica is generally tolerated well at therapeutic doses, but potential risks include:

• Gastrointestinal upset (nausea, mild diarrhea) at high doses.
• Allergic reactions—rare hives or contact dermatitis after topical use.
• Possible interference with thyroid hormone absorption; avoid concurrent consumption with levothyroxine.
• Noticeable blood-thinning action—caution if combining with warfarin or NSAIDs.
• Contraindicated in pregnancy & lactation due to insufficient safety data.

Long-term high-dose ingestion (>12 g/day) may stress renal clearance. Always inform your physician and Ayurvedic vaidya about existing conditions, and do not self-prescribe if you have autoimmune disorders or bleeding tendencies.

Modern Scientific Research and Evidence

The resurgence of interest in Capparis zeylanica has spurred several recent studies:

• 2021 Ethnopharmacology trial: Human pilot (n=30) showed hepatoprotective benefit—55% reduction in ALT levels with 3 g/day extract over eight weeks.
• 2019 Phytochemistry analysis: Identified six novel isothiocyanates in bud essential oil, broadening the known phytochemical profile.
• 2020 Journal of Herbal Medicine: Demonstrated synergy between quercetin-rich leaf extract and ampicillin against MRSA strains in vitro.
• 2022 Clinical observation: Topical ointment standardized to 5% saponins promoted 25% faster healing of diabetic foot ulcers in a small case series.

These findings largely mirror traditional claims of liver support, antimicrobial action, and wound healing. However, large-scale randomized controlled trials are still scarce. Ongoing debates center on optimal standardization markers (glucocapparin vs total flavonoid content) and best extraction solvents for maximal bioactivity. More in vivo human studies are essential to move from folklore to firmly evidence-based practice.
