A Proven, Research-Backed Itch & Rash (Dry) Formula
Modern research on traditional herbs commonly used in formulas for dry, itchy skin, including Rehmannia Root (Sheng Di Huang), Angelica Root (Dang Gui), Asparagus Root (Tian Men Dong), Dwarf Lilyturf Root (Mai Men Dong), and Black Cohosh Rhizome (Sheng Ma), has explored their effects on antioxidant activity, inflammatory pathways, skin barrier support, and overall skin wellness. Research has shown that several of these herbs contain naturally occurring compounds that help support healthy immune regulation, protect skin cells from oxidative stress, and promote normal skin repair and hydration.
Additional studies have investigated the traditional use of Rehmannia Root and Angelica Root for supporting healthy circulation, nourishing Blood, and maintaining skin integrity, while Asparagus Root and Dwarf Lilyturf Root have been studied for their moisturizing, antioxidant, and tissue-supporting properties. These herbs have been widely used in Traditional Chinese Medicine to help replenish Yin, nourish Blood, and support healthy skin affected by dryness and irritation.
From a Traditional Chinese Medicine perspective, dry, itchy skin is often associated with Blood Deficiency, Yin Deficiency, and Dry Heat. When Blood and Yin are nourished and internal dryness is reduced, the skin is traditionally believed to receive better nourishment, helping maintain healthy hydration, comfort, and overall skin balance.
