Gotu kola (Centella asiatica) contains triterpenes including asiaticoside and madecassoside that stimulate collagen synthesis and reduce inflammation. These compounds enhance wound healing, improve skin elasticity, and reduce signs of aging through direct fibroblast activation.
Reported Benefits (Provisional)
Origin & History
Gotu Kola, also known as Centella asiatica, is a perennial plant native to Asia. It is harvested for its leaves, which are used in extracts and supplements for their potential skin-healing properties.
Research Narrative (Provisional)
Research, including RCTs, indicates that Gotu Kola may aid in wound healing and improve skin elasticity, although more comprehensive studies are necessary to confirm these findings.
Preparation & Dosage
Dosage guidance is withheld because the publication gate has not recorded adequate support for this profile.
Nutritional Profile
Gotu Kola (Centella asiatica) contains triterpene saponins as its primary bioactive compounds, predominantly asiaticoside (approximately 0.1–8% in standardized extracts), madecassoside (0.1–2%), asiatic acid, and madecassic acid — collectively termed 'centelloids.' Standardized oral supplements typically deliver 40–70% total triterpenes per dose (common doses: 60–180 mg extract). It contains flavonoids including quercetin, kaempferol, and rutin (trace levels, ~0.1–0.5%), as well as polyacetylenes and volatile oils. Phytosterols (beta-sitosterol, stigmasterol) are present at low concentrations. Macro/micronutrient content is modest: it provides small amounts of vitamin C (~5–15 mg/100g fresh leaf), B vitamins (thiamine, riboflavin at trace levels), calcium (~170 mg/100g), iron (~5.6 mg/100g), and zinc. Chlorophyll and beta-carotene contribute antioxidant capacity in whole-leaf preparations. Bioavailability note: asiaticoside undergoes enzymatic hydrolysis in the gut and skin to free asiatic and madecassic acids, which are the pharmacologically active forms. Topical penetration is enhanced by lipid-based carriers due to the amphiphilic nature of triterpene saponins. Oral bioavailability is moderate, with Tmax around 4–5 hours for triterpene acids.
Reported Mechanism (Provisional)
Gotu kola's triterpenes, particularly asiaticoside and madecassoside, stimulate type I collagen synthesis by activating transforming growth factor-beta (TGF-β) pathways in fibroblasts. These compounds also inhibit inflammatory mediators including nuclear factor-kappa B (NF-κB) and reduce matrix metalloproteinase (MMP) activity. The bioactive compounds enhance microcirculation by strengthening capillary walls and improving venous tone through effects on endothelial nitric oxide synthase.
Clinical Narrative (Provisional)
Clinical studies demonstrate gotu kola's effectiveness in wound healing, with randomized trials showing 20-30% faster healing rates in surgical wounds when applied topically. A 12-week double-blind study of 87 participants found oral supplementation (60mg daily) improved skin hydration by 41% and reduced photoaging markers. Meta-analyses of venous insufficiency trials indicate modest improvements in leg swelling and circulation, though study quality varies. Most research focuses on topical applications rather than oral supplementation for skin benefits.
