Approach: human outcome. Palette: natural.

Close, low-angle shot of an older adult's bare lower leg and bare feet resting on crisp white hospital bed linen, with a soft, out-of-focus window in the background. The camera sits at mattress level and looks along the calf toward the ankle. Face is not visible. A small ultrasound probe coated in clear gel presses against the back of the knee. The operator's gloved hand enters from the frame edge. Soft overcast daylight from the window gives skin tones a warm, realistic look. Around the bed, a sprig of fresh rosemary and a few purple-green ashwagandha leaves sit on a wooden bedside tray. The leaves provide plant-green accents, along with one small electric green sensor light on a monitor. Palette: natural greens, wood browns and warm skin. Mood: quiet, careful and hopeful.

PB125:卧床期间维持动脉功能的植物性 Nrf2 混合物

BY NOVA CHEN ·

PB125 是一种由迷迭香、印度人参(ashwagandha)和黄酮类化合物 luteolin 组成的植物性 Nrf2 激活剂。近期一项小规模、双盲的人体试验在 44 名受试者中检验了其效果。24 名老年受试者每日服用 200 mg,连续两周后,上臂血流介导扩张(FMD)从 2.8% 提升至 3.8%,膝后血管 FMD 从 1.5% 提升至 2.3%。在随后五天的卧床期间,PB125 组的动脉功能和抗氧化水平保持稳定,而安慰剂组出现下降。年轻受试者虽然基线 FMD 未提升,但在肢体固定期间仍表现出对膝后 FMD 的保护。由于样本量小且仅使用替代终点,这一发现更像是积极信号,而非临床疗效的确凿证明。

**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 ·

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。

**Approach:** Macro science, with a touch of botanical realism. **Palette:** D, bold color field.

Extreme close-up, shot from slightly above at a 30-degree angle, of freshly cut shatavari roots and dried ashwagandha root slices. The pale, tuberous shatavari roots show their moist, fibrous cross-sections. Beside them lie tan, rough-textured ashwagandha pieces with visible starchy grain. Both sit on a seamless saturated magenta backdrop, and a few fine powder particles are scattered across it. Soft, directional studio light from the left gives crisp highlights on the wet root surfaces and gentle, warm-neutral shadows with no blue cast. A tiny leaf of fresh green asparagus-fern foliage, in a hint of electric green, enters at the top corner. Shallow depth of field blurs the far root tips. The mood is vivid, confident and curious, with a clean editorial look.

BY NOVA CHEN ·

这两味在阿育吠陀中使用数百年的草药,近日完成了安慰剂对照试验。8 周、135 位女性的研究显示,单独服用 Shatavari 根提取物即可显著提升整体性功能和满意度;若与 Ashwagandha 联合使用,则在性欲、润滑、高潮、情绪和幸福感等方面有进一步改善。所有不良反应均为轻微。
