(1) Primarily treats carbuncles and swellings. For patients with erysipelas sores, mixing it with soil, pounding into a paste, and applying externally yields particularly good results. [Meng Shen]
(2) Its seeds are excellent for treatment. The red berries are named "Dragon Pearl" (Longzhu); long-term consumption can darken and promote hair growth, preventing aging. [Chen Cangqi]
(3) The taste is bitter; the juice should be removed before consumption. [Su Jing]
(1) For patients suffering from jaundice, fresh roots should be pounded, and the juice extracted and ingested for beneficial effects. [Su Jing]
(2) Additionally, it promotes the smooth functioning of the five Zang organs and lightens the body. It clears pathogenic factors from the Spleen and Stomach and eliminates various malignant heat toxins. Consuming small amounts is beneficial, but excessive intake causes cold qi to enter the sinews, leading to emaciation. While it can lighten the body and strengthen the person, it offers no other benefits. [Su Jing]
(3) People in certain regions harvest the roots to produce local yellow medicine. Furthermore, it stabilizes the Middle Jiao and benefits the five Zang organs; it can be boiled and eaten with sauce or made into a soup. [Meng Shen]
(1) Tonifies deficiencies of the five Zang organs. Leaves: induce movement of Qi. [Chen Cangqi]
(2) Shepherd's purse seeds (Jizi): used in formulas treating eye conditions. Do not consume together with flour, as this causes back oppression. Individuals taking cinnabar and sulfur pills (Dan Shi) must avoid eating it. [Su Jing]
(1) Tonifies deficiencies of the five Zang organs. [However, it causes] Qi stagnation in the meridians, collaterals, sinews, and bones, along with toxic vapors. It leads to weakness in the legs and inability to walk. It diminishes sexual function and shrinks the penis. Excessive consumption causes hair loss, nasal congestion, and dim vision. Children must not eat it, as they will immediately lose the ability to walk. [Chen Cangqi · Meng Shen]
(2) Additionally, individuals with cold constitutions who consume it may experience abdominal distension if eaten in large quantities. [Meng Shen]
(1) Treats the five types of jaundice: Pound fresh plants to extract juice, take one sheng per dose, twice daily, until recovery. [Meng Shen]
(2) Highly beneficial to humans; harmonizes the five Zang organs, brightens eyes and ears, dispels wind-heat, and makes the body light and agile. Long-term consumption is enjoyable; cooked consumption is preferred. Raw consumption induces vomiting of clear fluid. [Meng Shen]
Excessive consumption induces vomiting of clear fluid. It also unblocks stagnant Qi in the five Zang organs but damages Yang Qi. [Su Jing]
(1) Leaves: Warm nature. White part (Scallion white): Neutral nature. Primarily treats high fever and sweating due to Cold Damage (Shanghan); Wind Stroke (Zhongfeng), facial and ocular edema, bone and joint pain, and damage to hair and eyebrows. [Meng Shen]
(2) Scallion white and roots: Neutral nature. Promotes Qi circulation, primarily treating headache due to Cold Damage. [Meng Shen]
(3) Additionally, treats wind-water syndrome in sores, characterized by swelling, pain, and urinary retention/dysuria: Mix green leaves with dried ginger and Scutellariae Radix (Huangqin), boil to make a decoction, and soak/wash the affected area for immediate cure. [Su Jing · Meng Shen]
(4) Winter scallions are best, suitable for winter consumption, but should not be eaten in excess. They should only be used to harmonize the five flavors. For deficient individuals with Qi disorders, excessive consumption triggers upward rushing of Qi, causing closure and cessation of the five Zang organs, damaging the Stomach of deficient persons. It opens the joints and induces sweating, hence its warm nature. [Su Jing · Meng Shen]
(5) Small amounts are sufficient and can be made into tea or soup. Do not consume excessively, as it may draw Qi upward rushing, causing obstruction and cessation of the five Zang organs. It must never be combined with honey; consuming them together accelerates upward rushing of Qi and can be fatal. [Meng Shen]
(6) Additionally, stops epistaxis (nosebleed) and promotes urination. [Meng Shen]
