芜荑
味道辛，气性平。无毒。产于河东和河西地区，有大种和小种之分。大芜荑比榆荚大很多，气味臭得像（音同“信”）一样难以忍受；小芜荑比榆荚稍小，（一说：这就是榆荚。）味道辛，酿制酱料可以使用。凡是用于医疗，宜选用陈久的。但市场上收藏的，多用盐渍，严重失去了气味，入药没有功效。所以购买时，必须选择气味腥臭的为良材；如果进行炮制配合，务必经过火处理后才可使用。主治五脏内的邪气，杀灭寸白虫及三种寄生虫。化解食积，清除肠风，驱逐寒冷，止心痛。散除皮肤和骨节的风湿，治疗痔疮、疥疮、癣疮及皮肤溃烂。
雷丸
因形状像丸而得名。入药需经炮制使用，（用甘草煎汤浸泡一夜，更能解毒。）红色的会杀人（白色的为好。）忌与扁蓄、葛根同用，宜使浓朴、芫花、荔实。（指芫花、荔枝核。）可解除胃热，驱除虫毒。杀灭三种寄生虫的同时也能杀灭白虫，对男子有利而对女子不利。（这里的“利”不是利益的意思，而是疏利的意思。）主治癫痫狂躁奔走，治疗出汗恶风。又可制成磨积消食的膏剂，专门消除小儿的各种疾病。久服会导致阳痿，尤其应当谨慎。
杉材
宜州杉
味道辛，气性微温，属金，有火性，为阳。无毒。江南深山之中，多有栽植。树干类似松树而粗大劲直，叶子附着在枝条上生长如同刺针。越冬不凋谢，随时可以采收。煎煮服用，主治心腹胀痛以及突发的心痛，效果显著；淋洗患处，治疗风疹瘙痒疮疡以及蔓延至膝盖的疮疡，立即见效。杉节煮水浸泡，揉搓治疗香港脚肿痛；杉菌煎汤吞服，治疗心肺突发疼痛。（生长在老杉木上的。）
Wuyi (Torreya grandis Seed)
Taste: Pungent. Nature: Neutral. Non-toxic. Produced in Hedong and Hexi regions, with large and small varieties. The large Wuyi is much larger than elm seeds, with an odor as foul as "Xin" (a sound onomatopoeia for a bad smell), which is unbearable; the small Wuyi is slightly smaller than elm seeds (some say this is actually the elm seed itself). It has a pungent taste and can be used for fermenting sauces. For therapeutic purposes, aged material is preferred. However, those stored in the market are often salted, which severely diminishes their aroma and renders them ineffective when decocted for medicine. Therefore, when purchasing, one must select those with a fishy odor as superior; if processing for compounding, it must be passed through fire before use. It governs pathogenic qi within the five zang organs, kills Taenia saginata (pork tapeworm) and three types of intestinal parasites. It transforms food stagnation, eliminates wind-dampness in the intestines, expels cold, and relieves heart pain. It disperses wind-dampness in the skin and joints, and treats hemorrhoids, scabies, tinea, and skin ulcers.
Leiwan (Omphalia lapidescens)
Named for its pill-like shape. For medicinal use, it must be processed (soaking overnight in licorice decoction enhances its detoxifying effect). Red ones are poisonous (white ones are good). It is incompatible with Polygonum aviculare (Bianxu) and Pueraria lobata (Gegen), but compatible with Magnolia officinalis (Houpo), Daphne genkwa (Yuanhua), and Litchi chinensis seed (Lishi). It resolves stomach heat and驱 (expels) insect toxins. It kills three types of parasites and specifically white worms. It is beneficial for men but not for women (the term "beneficial" here refers to purgative/dredging action, not general benefit). It governs epilepsy with manic running, and treats sweating with aversion to wind. It can also be made into a paste for resolving accumulations, specifically to treat various diseases in children. Long-term use may cause impotence, so caution is advised.
Shancai (Cunninghamia lanceolata Wood)
Yizhou Shancai
Taste: Pungent. Nature: Slightly warm. Element: Metal. Contains Fire nature, Yang. Non-toxic. Planted extensively in the deep mountains of Jiangnan. The trunk resembles pine but is thicker and straighter; leaves grow attached to branches like needles. They do not shed in winter and can be harvested at any time. Decoction and oral administration are highly effective for epigastric and abdominal distension/pain and sudden severe heart pain. Washing with the decoction is immediately effective for urticaria, pruritic sores, and spreading knee ulcers. Boiling the nodes and soaking helps massage/treat swollen and painful feet (Hong Kong foot/jock itch context implies lower limb edema or fungal infection). Swallowing the decoction of the fungus (Shan'er) grown on old trees treats sudden pain in the heart and lungs.
