Experimental: Berberine Chloride
This study employed a randomized, double-blind, placebo-controlled, two-period crossover design: subjects were randomized into two groups of equal size. The random allocation was conducted by asking volunteers to select the randomized number generated by computer. Each number represented placebo or BBR, and each group has the same number of numbers. The dosing sequence in the first group was oral BBR in the first cycle and oral placebo in the second cycle. The second group was administered placebo in the first cycle and BBR in the second cycle. Take the second dose 14 days after the first dose. After the last dose, continue to observe for 14 days to watch for side effects. On each experimental day, after an overnight fast, the subjects received a single oral dose of 1 g of BBR or a corresponding dose of the placebo.
