For patients experiencing joint discomfort, numbness in hands and feet, or rheumatic pain, homemade chicken blood vine wine is recommended. Slice 30 grams of chicken blood vine and steep in 500 ml of 60-proof white liquor within a sealed porcelain jar. Simmer over water for 3–5 hours. Consume as desired.
Chicken Blood Vine is the dried stem of the leguminous plant Vigna angustifolia, sliced and used raw. Its pungent-sweet taste and warm nature promote blood circulation and invigorate meridians, addressing symptoms like lower back and knee soreness, limb numbness, and rheumatic pain caused by qi and blood deficiency.The Compendium of Materia Medica Supplement records it as "strengthening sinews and bones, alleviating soreness and pain... treating elderly qi and blood deficiency, numbness in hands and feet, paralysis, and similar conditions." Regular consumption of this wine effectively relieves the aforementioned symptoms.
