Small Water-pepper
Persicaria minor
Persicaria minor, commonly known as Knotweed or Biokesum, is a traditional plant used in some Asian and Chinese medicine practices. While its specific uses are not widely documented, it has been studied for potential health benefits. Scientific evidence suggests that Polygonum minus (a closely related species) 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. Additionally, a six-month study indicated potential improvements in visual memory, negative mood, brain-derived neurotrophic factor (BDNF), and triglyceride levels among older adults with mild cognitive impairment. The study also found that miR156a targets PmFBK2, which may influence stress-related protein interactions within the plant. Safety concerns are minimal; no major issues or drug interactions have been recorded to date.

What the science says
- Most studies suggest Polygonum minus shows potential antioxidative and anti-inflammatory effects, possibly due to its phenolic and flavonoid compounds.
- All three genotoxicity tests conducted on Biokesum® Polygonum minus (Persicaria minor) standardized extract were negative.
- Six months of Biokesum® supplementation potentially improved visual memory, negative mood, BDNF, and triglyceride levels among older adults with MCI.
- The study found that miR156a targets PmFBK2, potentially influencing stress-related protein interactions in Persicaria minor.
