Persicaria capitata (Polygonum capitatum)
This plant used to be known botanically as Polygonum capitatum but now has been reclassified into a new genus, Persicaria. It was introduced from Himalaya. It is a trailing plant. It is known also as Japanese Knotweed, Himalayan Smartweed and Pink Bubble Persicaria. Used in Traditional Chinese Medicine where its aerial parts are used to brew a tea which is consumed for the treatment of a range of urological disorders, such as kidney stones and urinary tract infections. An in-vitro study reported that traditional use of this plant for the treatment of urinary tract infections can be attributed to the presence of anti-bacterial and anti-inflammatory agents found in the plant. Persicaria capitata has also been found to contain antioxidants.
Favours moist rocky areas and full sunny area. This one is growing wildly near the gate.
