Centella asiatica contains triterpene saponins including asiaticoside and madecassoside that support cognitive function and wound healing. These compounds enhance collagen synthesis and may modulate GABA neurotransmitter activity in the brain.
Origin & History
Mandukaparni (Centella asiatica), also known as Gotu Kola, is a perennial herbaceous plant native to tropical regions of Asia, particularly India, and found in wetlands across Africa, Australia, and the Pacific. The herb is sourced from its aerial parts (leaves and stems) and typically prepared via aqueous or ethanolic extraction methods, yielding high levels of pentacyclic triterpenoid saponins, chlorogenic acids, and flavonoids.
Scientific Research
The research dossier reveals a notable absence of specific human clinical trials, RCTs, or meta-analyses with no PubMed PMIDs provided. While general references note pharmacological actions attributed to triterpenoids and saponins, no primary clinical data or study designs with sample sizes and outcomes are available in the current research.
Preparation & Dosage
No clinically studied dosage ranges for extracts, powders, or standardized forms are documented in the available research. Standardization parameters such as percentage of asiaticoside are not specified in any studies. Consult a healthcare provider before starting any new supplement.

How It Works
Centella asiatica's primary bioactive compounds asiaticoside, madecassoside, and asiatic acid enhance collagen synthesis by stimulating fibroblast proliferation and increasing hydroxyproline content. The triterpenes may modulate GABAergic neurotransmission and reduce cortisol levels, potentially explaining traditional anxiolytic uses. These compounds also demonstrate antioxidant activity by scavenging free radicals and supporting cellular repair mechanisms.
Clinical Evidence
Limited human studies suggest Centella asiatica may improve cognitive function and reduce anxiety symptoms, though most evidence comes from small preliminary trials with 20-40 participants. A few studies using 300-600mg daily extracts showed modest improvements in memory tasks and stress markers over 2-12 week periods. Wound healing applications show more promising results in clinical settings, particularly for diabetic ulcers and post-surgical recovery. However, large-scale randomized controlled trials are lacking for most claimed benefits.
Safety & Interactions
Centella asiatica is generally well-tolerated with mild side effects including drowsiness, stomach upset, and skin sensitivity in some individuals. It may enhance sedative effects of medications like benzodiazepines, barbiturates, and sleep aids due to potential GABAergic activity. Pregnant and nursing women should avoid use due to insufficient safety data. Individuals with liver disease should use caution as rare cases of hepatotoxicity have been reported with high-dose or prolonged use.
