Chinese knotweed
Persicaria chinensis
Persicaria chinensis is a plant traditionally found in East Asia. While there are no specific traditional uses recorded for this plant, it has shown promise in modern research. Scientific evidence indicates that oxalic acid from Persicaria chinensis can effectively repel pillbugs and tannins contribute to its antioxidant activity. Additionally, distinct miR319a from the plant targets ITGA3, leading to reduced viability and apoptosis in HeLa cervical cancer cells. The growth characteristics of Persicaria chinensis vary monthly, with peak leaf biomass observed in June and increased stem biomass throughout the period. No major safety concerns or drug interactions have been recorded for this plant.
