| Standard Dose | 500-1000 mg/day of seed extract (standardized to >8% polyphenols) or 10-15 seeds daily (traditional Ayurvedic dosing, escalated from 1 seed/day) | 250-750 mg as needed, maximum 1-2 times per week (for educational context — carries significant dependence risk) |
| 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. | On an empty stomach (food significantly reduces absorption). Onset 2-4 hours. Effects last 4-8 hours with residual effects up to 24 hours. Half-life approximately 5.3 hours. |
| Cycle Duration | Traditionally used in 30-60 day courses. No established cycling protocol from clinical data. | STRICTLY intermittent use only — maximum 1-2 times per week. NEVER use daily for more than 1 week. Tolerance develops within days, leading to dose escalation and dependence. |

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.

Beta-phenyl derivative of GABA that crosses the blood-brain barrier (unlike GABA itself) due to the addition of a phenyl ring. Acts as a full agonist at GABA-B receptors with 30-68x lower affinity than baclofen, requiring correspondingly higher doses. Also binds to and blocks alpha-2-delta subunit-containing voltage-dependent calcium channels (VDCCs), making it a gabapentinoid similar to gabapentin and pregabalin. At low concentrations, mildly increases dopamine levels in the brain, providing stimulatory and nootropic effects alongside anxiolysis. Weak agonist activity at GABA-A receptors at higher doses.
