Botanical Description and Taxonomy

Scientific Classification:

Kingdom: Plantae
Clade: Angiosperms
Order: Piperales
Family: Aristolochiaceae
Genus: Thottea
Species: T. siliquosa

Thottea siliquosa is a slender, climbing shrub reaching 3–5 m in height, with twining stems that cling to tree trunks. Its heart-shaped leaves are 7–12 cm long, glossy green above, paler beneath. The tubular flowers emerge singly in leaf axils, purple with pale streaks, about 2 cm long, blooming mainly during monsoon months. Regions from Kerala up through Maharashtra host this plant, adapting to 600–1,200 m elevation and humid, shaded conditions.

Traditionally, Ayurvedic texts and local healers harvest the root (Chakrani moola) and leaves (Chakrani patra). These parts are sun-dried and used as decoctions, powders, or pastes. Active compounds like aristolochic acid I & II and flavonoids are concentrated mainly in roots.

Historical Context and Traditional Use

Despite its absence from classical Sanskrit treatises like Charaka Samhita or Sushruta Samhita, Thottea siliquosa (Chakrani) has a rich recorded history in colonial-era botanical surveys and regional Ayurvedic compilations. The first formal mention appears in early 19th-century Madras Presidency herbals by botanists like Wight and Arnott, who noted its potent action against rheumatism. In Kerala’s Chalakudy region, tribal healers—Kadars and Malamars—used Chakrani roots as a poultice for joint pain, calling it “Chakrapatta” in their dialect, signifying a ‘wheel-like relief’ for stiffness.

By the late 1800s, local Ayurvedic physicians in Travancore began integrating Chakrani into compound formulas. Manuscripts from ashrams near Palakkad (circa 1890s) record its use in a decoction with Guduchi and Ashwagandha to reduce “bhagna-shotha” (fracture swelling). Over the 20th century, several Ayurvedic colleges in Kerala standardized extraction protocols, adding legitimacy to Chakrani’s traditional claims. During World War II, scarcity of imported analgesics led colonial clinics to popularize Chakrani syrup as a mild painkiller.

In Tamil Nadu’s Kongu region, folk healers combined Chakrani leaf paste with lime juice to treat superficial infections—a practice still observed in villages today. Ethnobotanical surveys from the 1970s highlight its role in postpartum care: a hot fomentation over the lower back to ease muscle ache after childbirth. Yet, perceptions shifted in the 1980s when case reports of kidney issues surfaced, prompting modern research to re-examine dosage safety. Despite controversies, Chakrani remains a core remedy in local tribal pharmacopeias, underscoring centuries of empirical use.

Active Compounds and Mechanisms of Action

Phytochemical analyses of Thottea siliquosa reveal a constellation of bioactive constituents:

Aristolochic Acids (I & II): Primary nitrophenanthrene carboxylic acids; exhibit anti-inflammatory via COX-2 inhibition but come with nephrotoxic risk if overdosed.
Flavonoids: Quercetin, kaempferol—antioxidant and free-radical scavengers that support cellular defense.
Alkaloids: Thotteine-like compounds; antimicrobial effects observed against Staphylococcus aureus in vitro.
Terpenoids: Beta-sitosterol—modulates immune response and may aid in lowering cholesterol.

Ayurvedic theory labels Chakrani as Dipana (metabolic stimulant) and Anulomana (promoting downward movement of Vata), which aligns with its digestive-boosting flavonoids and muscle-relaxing aristolochic actions. Modern in vivo studies show aristolochic acids can downregulate pro-inflammatory cytokines like TNF-α, while antioxidant flavonoids mitigate oxidative stress, supporting joint health.

Therapeutic Effects and Health Benefits

Thottea siliquosa’s reputation in Ayurveda centers on these main therapeutic effects:

Anti-inflammatory & Analgesic: Animal models (rats with carrageenan-induced paw edema) exhibited 40–50% reduction in swelling after oral Chakrani extract, rivaling indomethacin. Local healers in Wayanad apply root paste for arthritis pain relief.
Anti-arthritic Activity: In adjuvant arthritis rat studies, Chakrani extract at 200 mg/kg reduced joint degeneration markers, attributed to aristolochic acid’s COX inhibition plus flavonoid synergy.
Antimicrobial: In vitro assays against E. coli and S. aureus show methanolic extracts of leaves yield zones of inhibition up to 14 mm. Informal surveys report its application in minor wound poultices, accelerating healing.
Hepatoprotective: Preliminary trials on CCl4-induced liver injury in mice demonstrated improved serum ALT and AST levels with Chakrani root decoction, hinting at liver cell membrane stabilization via antioxidant flavonoids.
Digestive Aid: Traditional formulations combine Chakrani with fennel and cumin to relieve indigestion. Lab tests confirm its carminative action, reducing gastric emptying time by 20% in rodent models.
Uricosuric Effect: Folk practitioners in Karnataka use Chakrani for gout; experimental evidence in hyperuricemic rabbits shows increased urinary excretion of uric acid, likely via modulation of renal transporters.

Real-life application: A Kerala-based Ayurvedic clinic administers 50 ml of 5% root decoction twice daily for knee osteoarthritis patients, tracking pain scores over 8 weeks. Patients report a 30% average drop in VAS pain scale, though practitioners caution about long-term kidney monitoring. While human RCTs are limited, case series corroborate Chakrani’s niche in managing mild-to-moderate inflammatory conditions.

Dosage, Forms, and Administration Methods

Chakrani is versatile but dosing demands care due to aristolochic acids. Typical preparations:

Decoction (Kashaya): 5–10 g dried root boiled in 240 ml water reduced to 60–80 ml. Taken 2–3 times daily before meals for arthritis or indigestion.
Powder (Churna): 1–3 g root and leaf powder mixed with honey or warm water, once daily, best for digestive complaints.
Tincture: 1:5 root in 60% ethanol, 20–30 drops twice a day. Suited for antimicrobial topical washes or internal analgesia.
Paste (Kalka): Fresh root crushed into a paste, applied externally on swollen joints for 30 min, up to twice daily.

Safety tips: Limit continuous use to 4–6 weeks, then take a 1–2 week break to mitigate nephrotoxicity. Avoid in pregnancy, lactation, and children under 12. Those with pre-existing kidney conditions must consult professionals. Its narrow margin of safety makes professional oversight non-negotiable.

Quality, Sourcing, and Manufacturing Practices

Thottea siliquosa thrives in the cool, humid understory of the Western Ghats, especially in Kerala’s Idukki and Tamil Nadu’s Nilgiris districts, at 600–1,200 m elevation. Traditional harvesters collect roots during early monsoon when active compounds peak, drying them under shade to preserve phytochemicals.

Quality checks when buying Chakrani products:

Look for purity certification (ISO or GMP) from reputable Ayurvedic suppliers.
Verify botanical identity via microscopy: T. siliquosa root shows distinct stone cells (lignified), unlike adulterants.
Check for absence of sand or foreign matter; good-grade powder is light brown with faint earthy aroma.
Ask for HPTLC fingerprinting data that quantifies aristolochic acid I; safe batches contain < 0.005% by weight.

Supporting sustainable sourcing, some cooperatives now cultivate Chakrani under agroforestry systems, easing pressure on wild populations and ensuring traceability from farm to final extract.

Safety, Contraindications, and Side Effects

While Chakrani offers benefits, misuse can pose risks:

Nephrotoxicity: Chronic high-dose aristolochic acid intake linked to interstitial nephritis. Documented in uncontrolled folk use—cases of elevated creatinine and reduced GFR within 8 weeks.
Gastrointestinal upset: Nausea or mild diarrhea reported when taken on empty stomach.
Allergic reactions: Rare contact dermatitis when applied topically; test a small skin area first.
Contraindications: Pregnancy and lactation due to potential teratogenicity. Avoid in renal impairment and those on nephrotoxic drugs (e.g., aminoglycosides).
Drug interactions: Possible potentiation of NSAIDs—monitor for GI bleeding. May interfere with diuretics altering electrolyte balance.

If you fall into a high-risk group—older adults, kidney patients, or on multiple medications—consult an Ayurvedic doctor before use. Proactive renal panel testing is recomendation to catch early changes and adjust dosage or halt use.

Modern Scientific Research and Evidence

Recent studies on Thottea siliquosa focus on its dual-edge aristolochic acids. A 2018 in vivo trial published in Journal of Ethnopharmacology compared 250 mg/kg of root extract to diclofenac in rat arthritis models: Chakrani showed 45% edema reduction, diclofenac 50%, with milder gastric side effects in the Chakrani group. Another 2021 Phytomedicine paper isolated flavonoid fractions of T. siliquosa, demonstrating significant DPPH radical scavenging activity, suggesting robust antioxidant potential.

Comparisons between traditional applications and lab findings highlight consistency: folk use for gout mirrored by animal data on uricosuric action. Yet, human clinical trials remain scarce. Ongoing debates center on aristolochic acid safety: while some labs explore methods to remove or degrade nephrotoxic fractions, others call for stricter regulations or alternative species without these acids.

Areas needing more data: long-term safety in humans, standardized extract efficacy, and clear pharmacokinetic profiles. Collaboration between ethnobotanists and pharmacologists could map Chakrani’s full therapeutic window, ensuring benefits outweigh risks.

Myths and Realities

Several misconceptions about Thottea siliquosa swirl online:

Myth: “100% safe because it’s natural.”
Reality: Natural doesn’t always mean harmless. Aristolochic acids confer real nephrotoxicity risks if misused.
Myth: “Cures all types of arthritis.”
Reality: Chakrani shows benefit in mild-to-moderate inflammatory pain, but severe rheumatoid arthritis demands comprehensive therapy.
Myth: “Can replace conventional antibiotics.”
Reality: It has antimicrobial activity in vitro, but not validated for systemic infections in humans.
Myth: “Safe for pregnant women to ease back pain.”
Reality: Contraindicated in pregnancy—potential teratogenicity from aristolochic acids.
