Li Dongyuan stated: When the pulse is wiry and qi is deficient, with dry and withered skin and hair, and hair loss, Huangqi Jianzhong Tang (Astragalus Decoction to Establish the Middle) should be used as the primary treatment. For hair loss accompanied by pain below the umbilicus, Sijunzi Tang (Four Gentlemen Decoction) added with Shudihuang (Rehmanniae Radix Praeparata) should be administered.

Zhu Danxi treated the son of the Hu family, aged seventeen or eighteen, whose hair had completely fallen out without a single strand remaining. His diet and daily activities were normal. The pulse was slightly wiry and choppy, consistent in both light and heavy pressure. This condition resulted from consuming rich flavors, leading to internal heat and dampness, with phlegm turbidity lodged in the diaphragm. Furthermore, his frequent consumption of plums caused the sour flavor to astringe the heat-damp phlegm, which then ascended with the rising qi to the head. This steamed and scorched the blood at the hair roots, gradually causing them to wither, resulting in sudden total hair loss. He prescribed herbs for nourishing blood and dispersing upward, using Fangfeng Tongsheng San (Wind-Dispersing Universal Salvation Powder), removing Mangxiao (Natrii Sulfas), and stir-frying Dahuang (Rhei Radix et Rhizoma) three times with wine. This was combined with Sizhu Tang (Four Substances Decoction) prepared with wine, mixed together, and decocted into a small dose. It was frequently given to the patient mixed with water containing ash. After more than two months, upon re-examining the pulse, the heat-dampness had gradually resolved. Medication was stopped, and he was advised to maintain a bland diet for recuperation. Two years later, his hair had grown back to its original state, and he was cured. Sweet melon leaves can treat alopecia; crushing them to extract juice and applying it topically promotes hair growth. Zirong San (Nourishing Glory Powder) and Sansheng Gao (Three Sages Ointment) are used to treat hair loss where regrowth fails, stimulating new growth. One sheng of Sesame Seeds (Semen Sesami Nigrum) is roasted until black, pressed for oil, and applied to the scalp. The *Qianjin Fang* states: Boiling Hemp Leaves (Cannabis Folium) and Mulberry Leaves (Mori Folium) in rice-washing water, and washing the hair seven times, can promote hair growth up to six chi in length. For eyebrow loss, raw Banxia (Pinelliae Rhizoma) and Yangshi (Excrement of Ovis Aries) are burnt until charred, ground into equal parts powder, and applied mixed with ginger juice. Alternatively, Wuma Hua (flowers of black sesame harvested in the seventh lunar month) are dried in the shade, ground into powder, soaked in raw black sesame oil (Oleum Sesami Nigris), and applied nightly. "Wuma" refers to autumn sesame.

The axilla refers to the junction below the arm and above the lateral costal region, belonging to the Pericardium Meridian of Hand-Jueyin. (Zhu Danxi stated: Regarding manifestations arising from the combination of hand and foot yin and yang meridians, axillary swelling involves the Pericardium Meridian of Hand-Jueyin and the Gallbladder Meridian of Foot-Shaoyang). It is also associated with the Liver Meridian of Foot-Jueyin. (*Ling Shu* states: When pathogenic factors affect the liver, their qi stagnates in the bilateral axillae). The anterior aspect of the axilla belongs to the Lung Meridian of Hand-Taiyin. The posterior aspect belongs to the Heart Meridian of Hand-Shaoyin. The inferior aspect belongs to the Liver Meridian of Foot-Jueyin. Six cun below the axilla belongs to the Large Luo Vessel of the Spleen Meridian of Foot-Taiyin. (*Ling Shu* states: The Large Luo Vessel of the spleen is named Dabao, emerging three cun below the Yuanye acupoint, distributing across the chest and hypochondrium. Note: Dabao and Yuanye are acupoint names, each existing bilaterally. Yuanye is located three cun below the axilla in the depression; it is accessed by raising the arm.)
