Fishweed can be used medicinally, and some places also have the custom of eating fishweed. Medicinal fishweed and edible fishweed are different parts of the same plant, both of which are derived from Houttuynia cordata of the family Houttuyniaceae, but there are still some differences between the two.
1. Medicinal Fishweed: Generally, the above ground part of Houttuynia cordata is dried and used, or the fresh whole herb is used if fresh medicine is used, but generally the dried product is mostly used, which has the efficacy of clearing away heat and detoxifying poison (removing heat and poison from the body), eliminating carbuncle and pus (eliminating carbuncle and pus), and diuretic and diaphoretic (improving the problem of drenching urination and the problem of small amount of urine not passing through the urinal cavity).
Fishwort can be used in the treatment of lung carbuncle spitting pus, phlegm-heat asthma and cough, hot diarrhea, feverish drenching (burning and stinging pain is obvious when urinating, accompanied by frequent urination and urgent urination, and abdominal traction discomfort), carbuncle sores and other treatments.
2. Edible fritillaries: generally the root of fritillaries, so it is also called folded ear root.
The use of drugs should be under the guidance of a doctor, can not be used on their own, so as not to delay the condition.
