[Qinpi (Fraxinus Cortex)]
Taste: Bitter. Temperature: Slightly Cold. Toxicity: Non-toxic. Indications: Wind-cold-damp Bi syndrome (a disease pattern characterized by pain, numbness, and heaviness in the limbs and joints caused by wind, cold, and damp pathogens), sensation of chilling cold on the skin (describing a sensation as if cold water is sprinkled on the body), clearing heat, and green nebulae with white membranes in the eyes (cloudy obstructions appearing on the cornea or lens). Long-term consumption prevents graying of hair and lightens the body.
(Note: Qinpi was originally named "Qin Pi", produced in the prefectures of Shaanxi, and also found in Heyang. Its tree branches and trunks resemble those of sandalwood, all being greenish-blue. The leaves are slender without flowers or fruits. The bark has white spots but is not rough or cracked. When the bark is soaked in water, the water turns blue-green; when written on paper, it appears green. Such specimens are authentic.)
The Qin tree grows near water. Its bark tastes bitter and is cold in nature, with a blue-green color. It absorbs the essence of water marshes, possessing the blue-green hue, thereby inheriting the qi transformation of water generating wood. By inheriting the qi of wood and sprouting in spring, it can treat Bi syndromes caused by wind, cold, and damp pathogens, as well as the chilling cold sensation on the skin surface. By inheriting the qi of water, it clears heat; thus, its primary function is to eliminate heat. The eyes are the orifices of the Liver. When the qi of wood is abundant, the Liver qi becomes robust; therefore, it treats green nebulae and white membranes in the eyes. Hair is considered the surplus of blood. When the water essence of the Kidneys is sufficient, blood is also replenished; hence, long-term consumption prevents hair from turning gray and makes the body feel light.
[Zhu Ye (Bambusa Leaves)]
Taste: Bitter. Temperature: Cold. Toxicity: Non-toxic. Indications: Cough with rebellious Qi (coughing and wheezing with upward reversal of Qi), spastic stiffness of sinews, elimination of malignant sores, and killing small insects.
(Bamboo is very abundant south of the rivers. Therefore, Dai Kaizhi's *Zhu Pu* states: "Rare in the Nine Rivers, yet plentiful in the Five Ridges." The stem is straight and hollow in the middle, evergreen throughout the four seasons. Branches have nodes, and leaves grow at the nodes. Leaves always appear in groups of three, and branches in pairs. It flowers once every sixty years; after flowering and bearing fruit, the bamboo dies. There are many species of bamboo. The *Shennong Bencao Jing* uses Dan Zhu (Danzhu Bamboo), while later generations also used Danzhu and Kuzhu (Kuzhu Bamboo). A variety with thin shells is called Gan Zhu (Ganzhu Bamboo), which is also excellent. Bamboo inherits the water essence of winter; its roots are hard, and it favors growing towards the southeast. This indicates that its Qi inherits from the northwest, while its physical form faces the southeast. In winter, it nurtures shoots; in spring, it sprouts new branches; in summer, it sheds its sheaths; in autumn, it matures into culms, obtaining the Qi of the four seasons of Heaven and Earth.)
Bamboo leaves do not fall during winter and remain evergreen throughout the year. Not falling in winter is due to inheriting the marked Yang Qi of the Taiyang (Greater Yang) channel. Since the marked Yang of Taiyang is fundamentally cold, the taste is bitter and the temperature is cold. Remaining evergreen is due to inheriting the Qi of Jueyin (Terminal Yin) wind-wood. Wood governs spring generation, moving upward and outward; therefore, it treats cough with rebellious Qi. Spastic stiffness of sinews occurs because the Liver governs the sinews. Bamboo leaves inherit the essence of wind-wood and can nourish the deficiency and spasticity of the Liver. Eliminating malignant sores works because malignant sores are primarily associated with heat. Bamboo leaves inherit the cold nature of water and can clear the fire-heat of the Heart. Insects belong to the Yin category. Bamboo leaves obtain the marked Yang Qi of Taiyang, causing small insects to die naturally.
