Pegagan (Centella asiatica)

Centella asiatica contains triterpene saponoids including asiaticoside and madecassoside that may support wound healing and cognitive function. This traditional Jamu ingredient has limited clinical evidence but shows preliminary bioactivity in laboratory studies.

Origin & History

Pegagan (Centella asiatica) is a tropical plant whose leaves contain bioactive triterpene saponins including asiaticoside, asiatic acid, madecassoside, and madecassic acid. The plant is traditionally extracted through maceration, though modern methods like microwave-assisted extraction (MAE) and ultrasound-assisted extraction (UAE) offer improved efficiency in isolating these compounds.

Historical & Cultural Context

Pegagan is categorized under the Jamu traditional medicine system. No specific historical or cultural context was provided in the extraction-focused research dossier.

Health Benefits

• Limited clinical evidence available - extraction methods documented but human trials not provided in research
• Traditional use in Jamu medicine system (evidence quality: Traditional only)
• Contains triterpene saponins and polyphenols with potential bioactivity (evidence quality: Preliminary - chemical analysis only)
• MAE extraction yields 26% higher phenolic content than traditional methods (evidence quality: Technical data only)
• UAE and Soxhlet methods successfully extract bioactive compounds (evidence quality: Technical data only)

How It Works

Triterpene saponoids like asiaticoside and madecassoside may enhance collagen synthesis by stimulating fibroblast activity and increasing type I collagen production. Polyphenolic compounds in Centella asiatica potentially modulate inflammatory pathways by inhibiting NF-κB signaling. The bioactive compounds may also influence GABAergic neurotransmission, though specific receptor interactions require further research.

Scientific Research

The provided research focuses exclusively on extraction methodologies rather than clinical trials. No human studies, RCTs, or meta-analyses with PMIDs were included in the research dossier. The available data pertains only to extraction efficiency and compound identification.

Clinical Summary

Clinical evidence for Centella asiatica remains limited with few well-controlled human trials available. Traditional use in Jamu medicine systems provides historical context but lacks quantified therapeutic outcomes. Laboratory studies have documented extraction methods and identified bioactive compounds, but translation to human efficacy is not established. Most available research focuses on compound identification rather than clinical effectiveness in human populations.

Nutritional Profile

Pegagan (Centella asiatica) is a low-calorie leafy herb with modest macronutrient content: approximately 2.0–3.5g protein per 100g fresh weight, 1.2–2.0g fat, and 5.0–7.0g total carbohydrates, with dietary fiber estimated at 1.5–2.5g per 100g. Moisture content is high at approximately 88–92%. Key micronutrients include calcium (170–200mg/100g dry weight), iron (3.1–5.6mg/100g dry weight), potassium (~390mg/100g fresh weight), and vitamin C (estimated 20–30mg/100g fresh weight, though heat-sensitive and degraded in cooking). Vitamin A precursors (beta-carotene) are present at low-to-moderate levels (~1,200–2,500 µg RAE/100g dry weight). The primary bioactive signature lies in its triterpene saponins: asiaticoside (0.1–0.9% dry weight), madecassoside (0.1–0.7% dry weight), asiatic acid, and madecassic acid — collectively termed 'centelloids,' typically comprising 1.0–8.0% of dry extract depending on growing conditions and extraction method. Total phenolic content ranges from 8–22mg GAE/g dry weight under conventional extraction, rising to approximately 28–32mg GAE/g dry weight under microwave-assisted extraction (MAE), reflecting the 26% yield advantage documented. Flavonoids including quercetin, kaempferol, and rutin are present at 2–6mg/g dry weight. Bioavailability of centelloids is considered moderate; asiaticoside undergoes hydrolysis to asiatic acid in the gut, which shows better intestinal absorption. Polyphenol bioavailability is subject to matrix effects and is enhanced by mild processing. No significant antinutritional factors are currently documented at typical consumption levels.

Preparation & Dosage

Synergy & Pairings

Insufficient data - no synergistic ingredients documented in extraction research

Safety & Interactions

Centella asiatica is generally considered safe when used traditionally, though comprehensive safety data from clinical trials is lacking. Potential side effects may include gastrointestinal upset or skin sensitivity in some individuals. No well-documented drug interactions are reported, but caution is advised when combining with medications metabolized by liver enzymes. Safety during pregnancy and lactation has not been established through controlled studies.
