Japanese Knotweed 虎杖 (36g)

Japanese Knotweed (Hu Zhang) — Natural Herbal Additive for Handmade Soap

Japanese Knotweed (Polygonum cuspidatum) is a highly unique and practical natural herbal additive. Rich in specialized phytochemicals, it is perfect for handmade soap making via oil infusion (infusion oil) or water decoction (soap-making water).

The root of Japanese Knotweed contains a high concentration of Resveratrol, a powerful antioxidant that remains partially active even after the saponification process. It helps combat free radicals, boosting the soap's anti-aging benefits and repairing skin dullness.

Additionally, Japanese Knotweed possesses excellent heat-clearing, detoxifying, and anti-inflammatory properties. For "problem skin" prone to acne, inflammation, eczema, or itchiness, soaps infused with this herb offer gentle soothing effects, reducing localized inflammation and redness. In Traditional Chinese Medicine (TCM), it is known to "invigorate blood and disperse stasis," which translates to improving skin microcirculation, correcting dullness, and promoting a healthier, more radiant complexion after washing.

虎杖是一種非常獨特且實用的天然草本添加物。由於它含有豐富的特殊化學成分，將其經由植物油浸泡（浸泡油）或煮水（入皂水）萃取後加入手工皂。虎杖根部含有大量的白藜蘆醇（Resveratrol）。這種強效抗氧化劑在皂化反應後仍能發揮部分作用，有助於對抗皮膚自由基，提升手工皂的抗衰老與肌膚修護暗沉的效果。虎杖具有優秀的清熱解毒、消炎特性。對於容易長痘痘、發炎、或患有濕疹、皮膚瘙癢的「問題肌」而言，使用虎杖萃取的手工皂能起到溫和舒緩、減輕局部發炎與泛紅的作用。中醫認為虎杖能「活血祛瘀」，體現在皮膚護理上，則有助於促進皮膚微循環，調理暗沉，讓洗後的膚色看起來更健康。
