Berberis aristata (Indian barberry)
What it is
The traditional Ayurvedic source of berberine, known as Daruharidra. Contains additional alkaloids including palmatine and jatrorrhizine that may enhance the metabolic effects of berberine. A 2024 RCT found 500 mg twice daily significantly improved HbA1c in type 2 diabetes. Also used traditionally for eye infections and as a bitter digestive tonic. Same drug interaction profile as berberine.
Dose
500–1,000 mg/day standardised root extract; equivalent berberine content to Coptis-derived supplements
Time of day & tips
Take with meals. Same drug interaction cautions as berberine — avoid with metformin, CYP substrates, and statins without medical guidance. The yellow staining of clothes and skin is normal and harmless.
