Approach: Macro science. Palette: B, warm.

Extreme macro photograph of raw berberine: a small heap of vivid yellow-orange crystalline powder with needle-like crystal clusters, shot at a low 30-degree angle with a shallow depth of field. Beside it, a dry sliver of Berberis root bark shows its bright yellow inner wood and fibrous grain. The surface is a smooth dark walnut board. Low golden-hour side light from the left makes the crystals glint like amber glass and throws long warm copper shadows across the wood. One tiny electric green highlight reflects off a glass spatula edge in the soft background blur. The mood is quiet and investigative, with rich saturated honey and burnt-orange tones and no blue cast. Photorealistic, microscopy-like texture, no text or labels.

小檗黄碱 vs 二甲双胍：HbA1c 从 9.5% 降至 7.5% 的先导试验解析

BY HELIX WARD · 2026年10月15日

2008 年的一项小规模先导试验直接比较了小檗黄碱与二甲双胍在新诊断的 2 型糖尿病患者中的降糖效果。结果显示，小檗黄碱组的 HbA1c 在 3 个月内从 9.5% 降至 7.5%。另一项在已有治疗基础上加服小檗黄碱的研究（48 例）亦观察到 HbA1c、胰岛素抵抗等指标的显著改善。但两项研究样本量均不足，约三分之一的受试者出现胃肠道不适。本文将解读这些数据能说明什么、不能说明什么，并给出在考虑使用小檗黄碱前应了解的关键要点。
