Caowutou (Aconiti Kusnezoffii Radix): The drug property is extremely drying, capable of opening up stubborn phlegm. It tastes bitter and pungent, and its nature is extremely hot. It can search out wind pathogens and overcome dampness, and open up stubborn phlegm. It treats stubborn sores; by using toxicity to combat toxicity, its effect surpasses that of Chuanwu (Aconiti Radix). However, it is extremely toxic, and without proper processing/preparation, it must not be administered lightly. It grows wild, resembling Chuanwu in shape, and is also known as Wu Hui (Aconiti Kusnezoffii Radix lateralis preparata). It is stir-fried with ginger juice or boiled with tofu for use. When boiled down into a paste, it is named She Wang (Aconitum Alkaloid Paste), used to coat arrows for hunting beasts; if it contacts the face, death occurs immediately.

Baifuzi (Typhonii Rhizoma): The drug property is drying, capable of dispelling wind-dampness and treating facial diseases. It tastes pungent and sweet, is toxic, and its nature is extremely hot, belonging to pure Yang. It is a herb entering the Yangming Meridian, capable of guiding the medicinal force upward, treating various diseases of the face (the Yangming meridian encircles the face; Baifuzi can remove wandering wind from the head and face. Made into facial cream, it eliminates spots and blemishes). It tonifies Liver deficiency, dispels wind-phlegm, treats heart pain and blood bi (obstruction), various cold-wind conditions, stroke with loss of voice, and damp-itching of the genitalia. The root resembles a smaller version of Caowutou, about one cun long, with wrinkles and nodes, and must be processed before use (Tao Hongjing stated: This drug has been extinct for a long time, with no true authentic specimens remaining; currently, only those produced in Liangzhou exist).

Poguzhi (Psoraleae Fructus), also known as Buguzhi: The drug property is drying, capable of tonifying the Fire of the Mingmen (Gate of Life). It tastes bitter and pungent, and its nature is warm. It enters the Pericardium and Mingmen channels. It tonifies Minister Fire to unblock Sovereign Fire, warms the Dantian, strengthens Primordial Yang, and reduces urination (also treats enuresis). It treats five labors and seven injuries (labors of the five zang organs, injuries of the seven emotions), cold pain in the waist and knees, cold kidney with seminal emission, and kidney deficiency diarrhea (Kidney deficiency leads to decline of Mingmen fire, which fails to steam and transform the Spleen and Stomach, resulting in Spleen-Stomach deficiency-cold, slow transformation and transportation, leading to reduced appetite, abdominal distension, borborygmus, vomiting of saliva, and diarrhea. This is like a pot without fire underneath; food will never cook. Therefore, tonifying the Mingmen Minister Fire is equivalent to tonifying the Spleen. Poguzhi 4 liang, Schisandra 3 liang, Nutmeg 2 liang, Evodia 1 liang, boiled with dates and formed into pills with jujube paste, named Sixiaowan (Four Spirits Pill), treats morning diarrhea). It treats women's blood and qi disorders (women's blood loss and qi sinking are similar to men's cold kidney and seminal emission) and miscarriage. Those from Southern Fan have a reddish color, while those from Lingnan are green. It is soaked in wine and steamed before use; some are soaked in child's urine or milk, or stir-fried with salt water. It pairs well with Walnut Kernel and Sesame Seed. It is incompatible with Licorice Root (Prescription of Chancellor Zheng of Tang: Poguzhi 10 liang, soaked in wine, steamed, and powdered; Walnut Kernel 20 liang, peeled and pounded into a paste, mixed with honey, taken daily with one spoonful adjusted with wine, or mixed with water. Bai Feixia stated: Poguzhi belongs to Fire, solidifying Primordial Yang; Walnut Kernel belongs to Water, moistening dryness and nourishing blood, possessing the wonder of mutual generation of Water and Fire. Avoid Brassica rapa var. trichocarpa and sheep blood. Adding Eucommia Bark creates Qing'e Wan (Green Young Pill). Yun Tai refers to Rapeseed).
