Gotu kola (Centella asiatica) contains bioactive triterpenes including asiaticoside, asiatic acid, and madecassoside that may support wound healing and cognitive function. The herb works primarily by modulating collagen synthesis and potentially affecting neurotransmitter pathways.
Origin & History
Gotu Kola (Centella asiatica) is a perennial herbaceous plant native to tropical wetland regions of India, Sri Lanka, and Southeast Asia, belonging to the Apiaceae family. The herb is sourced from its leaves, stems, and whole plant, with extracts typically obtained through solvent extraction in glycerin and water or by finely chopping the plant material.
Research Narrative (Provisional)
The research dossier does not provide specific human clinical trials, RCTs, or meta-analyses with PMIDs. While general pharmacological activity is attributed to triterpenes, no factual clinical trial data including study designs, sample sizes, or outcomes is available in the current sources.
Preparation & Dosage
Dosage guidance is withheld because the publication gate has not recorded adequate support for this profile.
Nutritional Profile
Gotu Kola (Centella asiatica) is a non-caloric medicinal herb used primarily for its bioactive phytochemical content rather than macronutrient value. Key bioactive compounds include: Triterpenoid saponins (primary actives) - asiaticoside (approximately 0.1–0.9% dry weight), madecassoside (approximately 0.3–1.0% dry weight), asiatic acid (approximately 0.5–1.0% dry weight), and madecassic acid (approximately 0.3–0.7% dry weight); these four compounds collectively constitute the 'total triterpenic fraction of Centella asiatica' (TTFCA), typically standardized to 40% in commercial extracts. Flavonoids present include quercetin, kaempferol, and rutin at trace concentrations (0.01–0.05% dry weight). Polyacetylenes including centellicin are present in small amounts. Macronutrients per 100g fresh leaf: crude protein approximately 2.3–3.0g, crude fiber approximately 1.8–2.5g, carbohydrates approximately 4.5–6.0g, fat less than 0.5g. Micronutrients include vitamin C (approximately 48–70mg/100g fresh weight), vitamin B2/riboflavin (trace), calcium (approximately 171mg/100g), iron (approximately 3.1mg/100g), and potassium (approximately 391mg/100g). Bioavailability notes: Triterpenes show moderate oral bioavailability with Tmax of 2–4 hours post-ingestion; distribution studies confirm tissue-level uptake in brain, skin, and gastric mucosa. Asiaticoside undergoes hydrolysis to asiatic acid in the gut, which is considered the primary absorbed form. Lipid-based delivery systems and phospholipid complexes have shown enhanced bioavailability in preliminary studies. Chlorogenic acid derivatives and hydroxycinnamic acids are also present as minor phenolic constituents.
Reported Mechanism (Provisional)
Gotu kola's triterpenes, particularly asiaticoside and asiatic acid, stimulate collagen synthesis by increasing fibroblast activity and enhancing type I collagen production. These compounds may also modulate GABA neurotransmission and reduce neuroinflammation through inhibition of pro-inflammatory cytokines. Additionally, the herb appears to strengthen venous walls by promoting glycosaminoglycan synthesis in blood vessel connective tissue.
Clinical Narrative (Provisional)
Human studies on gotu kola are limited but show some promise for venous insufficiency and wound healing. A few small trials (20-100 participants) suggest 60-120mg daily may improve venous circulation and reduce ankle swelling. Cognitive studies are primarily animal-based, with minimal human data available. The overall clinical evidence remains insufficient to establish definitive therapeutic benefits, requiring larger, well-controlled trials.
