Yuganzi (Phyllanthus emblica). It resolves the toxicity of metallic and mineral substances. When ground into powder, it is taken by mixing with a decoction. The "Amla fruit" mentioned in Buddhist scriptures refers to this plant. Presumably, this plant also exists in the West.

(Kuang) [Referring to a specific form or variant, likely implying a resinous or crystalline substance] resembling sugar frost condensed on fine branches, growing in clusters, purple-black in color, turning red when ground. Currently, people use it to manufacture cotton-smoke脂 (mianyanzhi), but it has become increasingly difficult to obtain in recent times. Other properties are as recorded in classics.

This substance grows inside bamboo, appearing like yellow earth adhering to bamboo in patches. It cools the Heart meridian and dispels wind-heat, making it particularly suitable for pediatric use due to its mild and gentle nature.

It is similar to Mujun Gui (Osmoxylon herb), but thinner.

Its qi is relatively mild, with more dispersing and draining effects, but not overly harsh or fierce. It can be ground together with Chenxiang (Aquilaria wood) and taken as a powder mixed with water. It treats cold qi in the chest and abdomen very effectively and safely.

Generally, it is used to promote the circulation of stagnant blood. For contusions and injuries causing pain, it is dissolved and taken with wine. When blood stagnates, qi becomes obstructed and stasis forms; when qi is obstructed and stasis forms, the meridians become full and tense; when meridians are full and tense, pain and swelling occur. In cases where contusions affect the muscles and result in swelling, it is because the meridians are injured, causing qi and blood to fail to circulate, leading to obstruction and stasis, thus resulting in such symptoms.

Smoke from pine trees [referring to Pine Soot Ink]. There are counterfeit versions made from millet ash in the world, which should not be used. Only Pine Soot Ink (Songyan Mo) can be used in medicine, and among these, soot collected from a distance (Yuanyan) is considered best. Currently, the Kingdom of Goryeo sends ink as tribute to China; it is unknown what substances are mixed into it, and it is unsuitable for medicinal use. This reflects the principle of "not daring to taste what one does not understand." Additionally, it is used to treat severe hematemesis: take two qian of fine powder from good quality ink, dissolve it in white boiled water mixed with prepared Ejiao (Donkey-hide gelatin) solution, adjust the consistency appropriately, and take in one dose. It is especially suitable for patients with excess heat. Furthermore, within the Yan region, there is petroleum; its smoke is very dense, and the soot can be made into ink, black and glossy like lacquer, surpassing pine soot ink. The inscription reads "Yanchuan Shiye" (Liquid Stone from Yanchuan). This type of ink cannot be used in medicine and is noted here for reference.

The leaves resemble small Loquat leaves, but lack hair on the underside, appearing smooth and unwrinkled. They flower in the first and second lunar months. In winter, two leaves serve as flower buds; once opened, each bud contains over fifteen flowers, similar in size to Toona flowers, very delicate. Each bud is about the size of a bullet, forming a ball-like cluster. Each flower has six petals, and one inflorescence may have seven or eight such balls, pale greenish-white, with the petal tips slightly reddish. Once the flowers open, the stamens fill the bloom, so only stamens are visible, not petals. After flowering, last year's green leaves all fall off, and new leaves gradually grow. It is most suitable for treating kidney deficiency and weak legs. However, it is scarce in Jingluo (Beijing/Luoyang area), Hebei, Hedong, and Shandong, so people rarely use it. It is abundant in Hunan/Hubei, Jiangxi/Jiangsu, and the Two Zhe regions, so southern fruits are often used. Modern physicians absolutely do not use it.
