Small Water-pepper
Persicaria minor
Persicaria minor, also known as Polygonum minus, is a plant traditionally used in various Asian and traditional medicine practices. While specific uses are not well-documented, it has been studied for its potential health benefits. Scientific evidence suggests that Persicaria minor may have antioxidative and anti-inflammatory properties due to the presence of phenolic and flavonoid compounds. A standardized extract from Biokesum® Polygonum minus showed no genotoxic effects in three different tests and potentially improved visual memory, negative mood, brain-derived neurotrophic factor (BDNF), and triglyceride levels among older adults with mild cognitive impairment over a six-month period. The study also indicated that miR156a may target PmFBK2, influencing stress-related protein interactions within the plant. No major safety concerns or recorded drug interactions have been identified for Persicaria minor to date.
