Hairless woundwort
Stachys riederi var. japonica
Stachys riederi var. japonica is a plant traditionally not used in any known medical practices. Scientific studies have shown that its ethyl acetate fraction exhibits antioxidant and anti-diabetic activities, with minimal cytotoxicity observed in mice models of type 2 diabetes. Additionally, the essential oil from this plant has demonstrated fumigant and contact toxicity against grain storage insects and showed antioxidant and cytoprotective effects in UVA-irradiated human dermal fibroblasts by reducing reactive oxygen species production and inhibiting DNA damage. Notably, domestic sewage input was found to alter its growth environment but did not directly impact the plant's medicinal properties. No major safety concerns or known drug interactions have been recorded for this plant.
