那些被称为“通”的药材，外形类似槟榔。产于南海山谷。
广州有一种另外的龙眼，形状像荔枝但较小，并非益智（一种药材），恐怕是当地人起了别名，现在所说的益智才是正确的名称，食用它们都对人有好处。
【谨案】益智，外形像连翘的种子，头部未开裂的，味道甘甜、辛辣，完全不像槟榔。它的苗、叶、花、根与豆蔻没有区别，只是种子较小罢了。龙眼又名益智，但益智并不是龙眼。那种龙眼树，外形像荔枝，叶子像林檎（苹果类植物），花朵白色，果实像槟榔，有鳞片状甲壳，大小如野鸡卵，味道甘酸。
味苦，性温、大温，无毒。主治中风、伤寒、头痛、寒热往来、惊悸、气血痹阻、肌肉坏死，驱除三种寄生虫，温暖中焦，益气，消痰下气，治疗霍乱及腹痛、胀满、胃中寒冷逆气、胸中呕吐不止、泄泻痢疾、淋证淋漓不尽、惊恐伤胃。一名浓皮，一名赤朴。
这种树的名称叫榛，它的果实名称叫逐相。治疗鼠瘰（淋巴结核），明目，益气。产于交趾、宛朐。三月、九月、十月采集树皮，阴干。
干姜作为其引经药，忌与泽泻、寒水石、硝石同用。现在出产于建平、宜都，以皮极厚、肉质紫色者为上品，壳薄且白色的不如前者。使用时需削去上层的粗糙外皮。
世俗方剂多用此药，道家养生则不需要它。
味甘、苦，性平，无毒。主治疟疾，解毒，辟除蛊毒、疰病等不祥之气，通利水道。长期服用可使身体轻盈并能延缓衰老。一名猪屎苓（因形似猪粪而得名）。二月、八月采集，阴干。
现在湘州、衡山没有，这条路不通，都从宁州运来。旧说这是枫树苓，其皮非常黑，结成块状像猪粪，所以以此命名，肉质白而坚实的为佳。
使用时需削去黑皮才称为合格药材，近年来特别难得。
Sweet in flavor, neutral in nature, non-toxic. It primarily treats pathogenic factors of the five Zang organs, calms the mind, alleviates anorexia, expels parasites, and eliminates toxins. Long-term consumption strengthens the Hun and Po (ethereal and corporeal souls), enhances auditory and visual acuity, lightens the body, and prevents aging.
Those referred to as "Tong" resemble Areca Seed (Binglang). They grow in the valleys of Nanhai.
In Guangzhou, there is another variety called Longyan, which resembles Lychee but is smaller; it is not Yizhi (Alpinia Oxyphylla Fruit), likely due to a local alias. The current Yizhi is the correct one, and consuming both is beneficial to humans.
[Recorded Investigation] Yizhi resembles the seed of Forsythia Fruit (Lianqiao); those with the head unopened have a sweet and pungent flavor, bearing no resemblance to Areca Seed. Its sprouts, leaves, flowers, and roots are indistinguishable from Cardamom Seed (Doukou), except that its seeds are smaller. Longyan is also named Yizhi, yet Yizhi is not Longyan. The Longyan tree resembles the Lychee tree; its leaves are like those of Malus asiatica (Linna); its flowers are white; its fruits resemble Areca Seed, possessing scaly armor, being as large as a pheasant's egg, and having a sweet and sour taste.
Bitter in flavor, warm and greatly warm in nature, non-toxic. It primarily treats Wind-Stroke, Cold Damage, headache, alternating chills and fever, palpitations, Bi syndrome of Qi and Blood, necrotic muscle tissue, expels three types of parasites, warms the Middle Jiao, benefits Qi, resolves phlegm and directs rebellious Qi downward, treats Cholera and abdominal pain, distension and fullness, cold rebellion in the Stomach, incessant vomiting in the chest, diarrhea and dysentery, strangury with dribbling, fright injuring the Stomach. It is also known as Nongpi and Chi Pu.
The tree is named Zhen, and its fruit is named Zhuxiang. It treats Shuluo (scrofula/lymphatic tuberculosis), brightens the eyes, and benefits Qi. It grows in Jiaozhi and Wanqu. The bark is harvested in the third, ninth, and tenth months and dried in the shade.
Dried Ginger (Ganjiang) serves as its guiding herb. It is incompatible with Alumen (Zexie), Aragonite (Hanshuishi), and Niter (Xiaoshi). Currently, it is produced in Jianping and Yidu. The best quality has extremely thick bark and purple flesh; those with thin shells and white interiors are inferior. When used, the rough outer crust must be scraped off.
It is widely used in secular prescriptions but is unnecessary for Daoist cultivation.
Sweet and bitter in flavor, neutral in nature, non-toxic. It primarily treats Malaria, detoxifies, wards off Gu poison, Zhu disease, and other inauspicious influences, and promotes urination. Long-term consumption lightens the body and delays aging. It is also known as Zhishiling (named for resembling pig feces). It is harvested in the second and eighth months and dried in the shade.
It is currently unavailable in Xiangzhou and Hengshan due to blocked trade routes; all supply comes from Ningzhou. Old texts state it is Fengshuling (Poria on Maple Wood); its skin is very black, forming lumps resembling pig feces, hence the name. White and solid flesh is preferred.
When used, the black skin must be scraped off to qualify. In recent years, it has been particularly difficult to obtain.
