Celastrus Paniculatus vs Gotu Kola (Centella asiatica)

Mechanism

Seed oil contains sesquiterpenes, alkaloids (celastrine, paniculatin), and polyunsaturated fatty acids that demonstrate dose-dependent cholinergic activity by inhibiting acetylcholinesterase (AChE) and increasing acetylcholine levels in hippocampal and cortical regions. Provides neuroprotection against oxidative stress through elevation of glutathione (GSH), catalase (CAT), and superoxide dismutase (SOD). Seed extracts attenuate hydrogen peroxide- and glutamate-induced excitotoxic injury in neuronal cells, and exhibit anti-inflammatory and anxiolytic properties.

Standard Dosing

500-1000 mg/day of seed extract (standardized to >8% polyphenols) or 10-15 seeds daily (traditional Ayurvedic dosing, escalated from 1 seed/day)

Timing

Morning, with or without food. Traditional practice involves gradual dose escalation starting from 1 seed daily, increasing by 1 seed per day up to 10-15.

Cycle Duration

Traditionally used in 30-60 day courses. No established cycling protocol from clinical data.

Side Effects

• GI distress
• Nausea (especially at higher doses)
• Diarrhea
• Sedation at high doses

Contraindications

• Pregnancy and lactation (insufficient safety data)
• Known allergy to Celastraceae family plants

Mechanism

Pentacyclic triterpenes — asiaticoside, madecassoside, asiatic acid, and madecassic acid — provide neuroprotection through multiple mechanisms: inhibition of acetylcholinesterase activity and enhancement of cholinergic transmission; reduction of phospholipase A2 (PLA2) activity to attenuate neuroinflammation; protection against beta-amyloid aggregation and tau hyperphosphorylation; and upregulation of BDNF to promote neuronal growth and synaptic plasticity. Asiaticoside enhances collagen synthesis and wound healing, while asiatic acid activates the MAPK/ERK pathway to promote neurite outgrowth.

Standard Dosing

500-1000 mg/day of standardized extract (35-45% triterpenes) or 750-1500 mg/day of whole herb extract

Timing

Morning or split morning/afternoon. With or without food. Acute mood effects (alertness, reduced anger) noted within 1 hour of dosing.

Cycle Duration

Ongoing; traditional use suggests no cycling required. Clinical trials run 2-6 months.

Side Effects

• GI discomfort
• Drowsiness
• Headache
• Skin irritation (topical use)
• Hepatotoxicity (rare, with prolonged high-dose use)

Contraindications

• Pregnancy (traditionally contraindicated; may have emmenagogue effects)
• Hepatic disease (rare hepatotoxicity reported)
• Scheduled surgery (may affect wound healing dynamics)
