汝南郡属豫州。今近道亦有，不堪用。惟用汉中、南郑、青弋，形大而长，尾间必有两

今汝南不复采用，惟以泾

【远志】
味道苦，性温，无毒。主治咳嗽气逆并损伤中焦（脾胃），补益身体不足，祛除邪气，通畅九窍（眼、耳、口、鼻及前后二阴），增强智慧，使耳目灵敏，记忆力强，意志坚定，体力倍增。对男子有益，能安定心气，止住惊悸，补益精气，去除心下膈间的积气，清除皮肤中的热邪，治疗面目发黄。长期服用可使身体轻盈不老，面色红润，延年益寿。其叶名为小草，主治补益精气，补养阴气，止住虚损引起的梦遗泄精。又名棘菀，又名绕，又名细草。产于泰山及宛朐的川谷地带。四月采集根和叶，阴干。与茯苓、冬葵子、龙骨配伍效果良好；能抑制天雄、附子的毒性；畏珍珠、藜芦、蜚蠊（蟑螂）、齐蛤（疑为百合）。据考证，药名中无“齐蛤”这一项，恐怕是“百合”之误。宛朐县属于兖州济阴郡，现在药材仍从彭城北面的兰陵运来。使用时需捣碎去心取皮，现在用一斤药材只能得到三两皮，市场上售卖的往往增加了分量。小草的形状像麻黄但颜色发青。远志也用于道教仙方中作为药用。
〔谨案〕《药录》卷下记载有齐蛤。
【泽泻】
味道甘、咸，性寒，无毒。主治风寒湿痹阻，乳汁不通，利水消肿，滋养五脏，益气力，使身体肥壮健壮。补益五劳七伤引起的虚损，去除泄精、消渴、淋沥不尽等症状，驱逐膀胱和三焦停滞的水液。长期服用可使耳目灵敏，不感到饥饿，延年益寿，身体轻盈，面色光泽，甚至传说能在水上行走。扁鹊说：多服会导致患者眼睛患病。又名水泻，又名及泻，又名芒芋，又名鹄泻。产于汝南的池泽地带。五月、六月、八月采集根部，阴干。畏海蛤、文蛤。其叶，味道咸，无毒。主治大风病，乳汁不出，难产，增强阴气，长期服用可使身体轻盈。五月采集。其果实，味道甘，无毒。主治风痹、消渴，补益肾气，增强阴气，补益不足，祛除邪湿。长期服用使面色光泽，但令人不育。九月采集。
汝南郡属于豫州。现在附近道路也有出产，但不堪使用。只有汉中、南郑、青弋产的泽泻，形状大而长，尾部必有分叉（两歧）才算好药。这种药材容易腐朽生虫，必须严密收藏。叶子狭长，丛生在浅水中。《仙经》中服食断谷的方法都使用它。也有说法称服用后身体轻盈，能在水上步行。
〔谨案〕现在汝南不再采用，只有以泾州、华州出产的为最好。
[Polygalae Radix (Yuanzhi)]
Taste: Bitter. Nature: Warm. Toxicity: Non-toxic. Indications: Mainly treats cough with counterflow qi and damage to the middle jiao (spleen and stomach); tonifies insufficiency; expels pathogenic factors; unblocks the nine orifices; enhances wisdom; improves hearing and vision, making them clear and acute; strengthens memory; stabilizes willpower; increases physical strength. Beneficial for men; calms the heart qi; stops palpitations and fright; benefits essence; removes stagnant qi under the heart and diaphragm; clears heat in the skin; treats yellowing of the face and eyes. Long-term use makes the body light, delays aging, improves complexion, and prolongs life. The leaves are named "Xiaocao" (Little Herb), mainly benefiting essence, supplementing yin qi, stopping deficiency-induced nocturnal emission. Also known as Jiwan, Rao, and Xicao. Grows in the valleys of Mount Tai and Wanqu. Roots and leaves are harvested in April and dried in the shade. It works well when combined with Poria (Fuling), Abutilon Seeds (Dongkuizi), and Dragon Bone (Longgu). It neutralizes the toxicity of Aconitum Lateralis Preparatum (Tianxiong) and Prepared Aconite Root (Fuzi). It is incompatible with Pearl (Zhenzhu), Veratrum (Lilu), Cockroach (Feilian), and Qige. According to records, "Qige" does not appear in standard pharmacopoeias, likely referring to Lily Bulb (Baihe). Wanqu County belongs to Jiyin Commandery, Yanzhou Prefecture; currently, medicinal materials still come from Lanling north of Pengcheng. When used, it should be crushed, the woody core removed, and only the bark taken. Currently, one jin of raw material yields only three liang of bark; market vendors often increase the quantity to deceive. Xiaocao resembles Ephedra (Mahuang) but is green. Polygalae Radix is also used in Daoist immortal formulas.
[Note] "Qige" is recorded in Volume 2 of *Yaolu*.
[Alismatis Rhizoma (Zexie)]

Bian Que stated: Excessive consumption causes eye disease in patients. Also known as Shuixie, Jixie, Mangyu, and Huxie. Grows in the ponds and marshes of Runan.

Harvested in September. Runan Commandery belongs to Yuzhou Prefecture. Although available nearby now, the quality is poor and unsuitable for use. Only those from Hanzhong, Nanzheng, and Qingyi are preferred, characterized by large size, long shape, and a forked tail, which is considered superior. This herb is prone to rotting and insect damage and must be stored tightly sealed. Leaves are narrow and long, growing in clusters in shallow water. *Xianjing* (Daoist Canon) uses it for grain-abstaining practices. It is also said to make the body light and enable walking on water.
[Note] Runan is no longer used; only those from Jingzhou and Huazhou are considered best.
