Hibiscus

Aside from being a beautiful flowering tree in your home, hibiscus promotes weight loss, & reduces the growth of bacteria and cancer cells.
the part used is the dried red calyx (the fleshy cup around the seed pod), not the showy petals.

the calyx lowers blood pressure by blocking the ACE enzyme and it relaxes blood vessels through nitric oxide-mediated vasodilation. also acts as a gentle diuretic.
in trials, 250 mg anthocyanin extract, or 2 to 3 cups of hibiscus tea a day made from about 10 g of dried calyx dropped blood pressure over 2 to 6 weeks, on par with the drug captopril.

it lowers total and LDL cholesterol and triglycerides and stops LDL from oxidizing, which is the first step in artery clogging.

hibiscus improves fasting glucose (around 4 mg/dL) and insulin resistance, and it inhibits adipogenesis (the formation of new fat cells) by downregulating PPAR-gamma and C/EBP-alpha. so if you want to be a skinny legend ig, drink this as a tea daily. it is acidic, so rinsing with water after drinking protects tooth enamel.
for the tea route: 2 to 3 cups a day (10g dried calyx) gives you the metabolic perks, blocks some fat-cell formation, slows fat and carb absorption.
for the studied fat-loss effect: you'd want a standardized hibiscus extract capsule, ~450 mg range, daily for about 12 weeks.

it can reduce absorption of chloroquine, lower simvastatin levels, raise diclofenac and caffeine levels, and it may interfere with some digoxin lab assays. space it away from medications and mention it to a prescriber.
