Oroxylum indicum (Indian trumpet tree) is an Asian medicinal plant whose standardized bark extract is sold as a dietary supplement for memory and focus. A single trial in older adults with memory complaints, co-authored by the extract's maker and not independently repeated, found better scores on some memory tasks but not overall thinking. Reported side effects are mild; possible drug interactions matter more. Long-term value remains uncertain. (Full Review)
| Marker | Target | Why |
|---|---|---|
| ALT | 10–25 U/L | Liver injury |
| AST | 10–25 U/L | Liver or muscle injury |
| Platelet count (complete blood count) | 200,000–300,000/µL | Bleeding-risk baseline |
| Fasting glucose | 75–90 mg/dL | Metabolic effect; hypoglycemia risk |
| HbA1c | 4.8–5.3% | 3-month glucose average |
| Fasting insulin | 2–6 µIU/mL | Insulin sensitivity |
| INR (if on warfarin) | Individual therapeutic target, usually 2.0–3.0 | Detects interaction |
| hs-CRP | Below 1.0 mg/L | Systemic inflammation |
| Serum BDNF | No established target; track change from own baseline | Research marker of nerve-cell support |
| Montreal Cognitive Assessment | 26–30 of 30; track change from own baseline | Global cognition |
Cadence: Baseline panel before starting; liver enzymes and blood counts at 4 and 12 weeks, then every 6–12 months; cognitive testing at 12 weeks, then every 6 months; glucose on the same cadence, more often with glucose-lowering drugs; INR 1–2 weeks after starting or changing dose (warfarin users)
