**Approach: Macro science. Palette: D, bold color field.**

Extreme macro photograph of freshly dug ashwagandha root, shot from a low three-quarter angle with a 100mm macro lens at shallow depth of field. One thick, pale tan root is cut cleanly across, showing its dense starchy cross-section, fine fibrous grain and a few clinging soil specks. It sits on a smooth, saturated tomato-red acrylic surface. A few small orange-red ashwagandha berries in papery husks blur softly behind it. Hard, direct studio light from the upper left casts crisp, warm-neutral shadows and a clean highlight along the cut face. A single tiny droplet of sap on the cut surface catches a pinprick of electric green reflection, the only green in the frame. The mood is bold, precise and skeptical-curious, with no text and no blue cast.

Ashwagandha 在高血压伴压力人群中降低血清皮质醇约 29％

BY NOVA CHEN · 2026年10月30日

最新研究显示：对于同时患有高血压且承受较大压力和焦虑的成年人，服用标准化 Ashwagandha 提取物后血清皮质醇平均下降约 29%。这是一项为期 60 天、双盲、安慰剂对照的 III 期临床试验（共 60 名受试者），同样观察到焦虑和感知压力评分的大幅降低。但需要注意的是，这些百分比仅是 Ashwagandha 组内部的变化，血压仅呈现出有利趋势，且研究作者与提取物生产商存在合作关系。下面我们一起看看该研究的具体发现、不能得出的结论以及哪些人需要慎用。
