【补遗部分】
【集解】李时珍说：大风子，现在海南周边的国家都有生长。据周达观《真腊记》记载：大风子是名为“大风”的大树的果实，形状像椰子但更圆。里面包含几十枚果核，大小如同雷丸（一种药材）。果仁呈白色，时间久了会变黄并出油，就不适合入药了。
【修治】李时珍说：提取大风子油的方法：取三斤大风子（去掉外壳及已经变黄油的部分），研磨至极烂，放入瓷器中，封口后放入滚水中，盖紧锅并密封，不让透气，用文火和武火交替煎煮至变成黑色膏状，称为大风油，可以和药物混合使用。
【气味】味辛，性热，有毒。
【主治】风癣、疥疮、癞病（麻风等皮肤顽疾）、杨梅疮（梅毒引起的溃疡）等各种疮疡，具有攻毒杀虫的功效。（李时珍）
【发明】朱震亨（字彦修，号丹溪）说：粗劣的医生治疗大风病时，辅助使用大风油。却不知道此物性热，虽有燥湿化痰的功效，但会损伤阴血，甚至导致患者在病情即将痊愈时先出现失明的情况。
李时珍说：大风油治疗疮疡，有杀虫和劫夺毒邪的功效，大概不可以多服。如果用于外涂，其功效是不可忽视的。
【附方】新收录五则。
治疗各种大风癞病：大风子油一两，苦参末三两，加入少量酒，制成糊状丸剂，大小如梧桐子。每次服用五十丸，空腹时用温酒送服。同时仍需用苦参汤清洗患处。（出自《普济方》）
治疗大风疮裂口：将大风子烧至存性（保留药性），与麻油、轻粉一起研磨涂抹。同时仍需用大风子壳煎汤清洗。（出自《岭南卫生方》）
治疗杨梅恶疮：方剂同上。
治疗风刺、赤鼻（酒渣鼻）：将大风子仁、木鳖子仁、轻粉、硫黄研成粉末，每晚用唾液调和后涂抹。
治疗手背皮肤皴裂：将大风子捣成泥状，涂抹患处。（出自《寿域神方》）

【释名】
【集解】某位医家（原文缺省，通常指前代本草作者）说：据徐表《南州记》记载：生长在南海人家园圃中。由大树生长而成，叶子圆形且有荚。近来蜀地种植也能成活。
李时珍说：树高两到三丈，叶子像梨叶但更圆。据宋祁《益部方物图》记载：红豆叶子像冬青树那样圆润光泽，春天开白花，在枝间结荚。果实累累如同串珠，比大红豆略扁，皮红肉白，因外形相似而得名，蜀人将其作为水果食用。
【气味】微寒，有小毒。
【主治】使人皮肤变黑、花癣（白癜风或色素减退性皮肤病）、头面部的游风（面部游走性红斑或瘙痒）。适宜用于制作面膜类化妆品及澡豆（古代清洁护肤用品）。（某位医家）
[Supplementary Records]
[Names] Li Shizhen stated: It is named so because it can treat "Da Feng" disease (leprosy).
[Collected Explanations] Li Shizhen stated: *Fengdazi* (Chilean Pine Nut) is found in various countries south of the Hainan region. According to Zhou Daguan's *Records of Zhenla*: The fruit comes from a large tree named "Da Feng," resembling a coconut but rounder. Inside are dozens of seeds, as large as *Leiwanzi* (a medicinal herb). The kernel is white; if left for too long, it turns yellow and oily, rendering it unsuitable for medicinal use.
[Preparation] Li Shizhen stated: The method for extracting *Fengdazi* oil is as follows: Take three jin (approx. 1.5 kg) of *Fengdazi* (remove shells and those that have turned yellow/oily), grind them into an extremely fine paste, place them in a porcelain vessel, seal the mouth, and submerge the vessel in boiling water. Cover the pot tightly to prevent air leakage. Boil using alternating mild and strong heat until it becomes a black paste, known as *Fengda You* (Wind Giant Oil), which can be mixed with other medicines.
[Properties and Flavor] Pungent, hot, toxic.
[Indications] Treats wind-related tinea, scabies, leprosy-like skin diseases, yaws (chancre), and various sores; has the function of attacking toxins and killing parasites (Li Shizhen).
[Elucidation] Zhu Zhenheng stated: Incompetent physicians treating "Da Feng" disease often adjunctively use *Fengda You*. They fail to realize that this substance is hot in nature; while it has the effect of drying dampness and resolving phlegm, it damages blood yin. There are cases where patients go blind before their illness is cured.
Li Shizhen stated: *Fengda You* treats sores by killing parasites and purging toxins, but it should not be taken internally in large doses. When applied externally, its efficacy is undeniable.
[Attached Prescriptions] Five new prescriptions.
For various forms of leprosy: One liang (approx. 37.5 g) of *Fengda You*, three liang of *Kushen* powder (*Sophorae Tonkinensis Radix*), mixed with a small amount of wine to form pills the size of *Wutongzi* (Chinese parasol tree seeds). Take fifty pills each time on an empty stomach with warm wine. Continue to wash the affected area with a decoction of *Kushen* (*Sophorae Tonkinensis Radix*) (from *Puji Fang*).
For cracked sores caused by leprosy: Burn *Fengdazi* until carbonized but retaining its properties, mix with sesame oil (*Sesami Oleum*) and *Qingfen* (Calomel), grind together, and apply topically. Also, wash with a decoction made from the shells (from *Lingnan Weisheng Fang*).
For malignant yaws sores: Same prescription as above.
For wind-induced prickles and rhinophyma (red nose): Grind kernels of *Fengdazi* and *Mubiezi* (*Strychni Semen*) with *Qingfen* and sulfur into a powder. Mix with saliva every night and apply topically.
For chapped hands: Mash *Fengdazi* into a paste and apply (from *Shouyu Shenfang*).
[Sea Medicines]
[Names]
[Collected Explanations] An unnamed physician stated: According to Xu Biao's *Nanzhou Ji*: It grows in gardens of households in the South Sea region. It grows from a large tree, has round leaves and pods. Recently, it has also been successfully cultivated in the Shu region.
Li Shizhen stated: The tree is two to three zhang (approx. 6-9 meters) tall, with leaves resembling pear leaves but rounder. According to Song Qi's *Yibu Fangwu Tu*: The red bean (*Hongdou*) leaves are round and glossy like holly (*Ilex chinensis*), blooming with white flowers in spring, bearing pods on branches. The fruits hang in clusters like beads, slightly flatter than large red beans, with red skin and white flesh. It is named for its resemblance [to other beans], and people in Shu consume it as a fruit.
[Properties and Flavor] Slightly cold, slightly toxic.
[Indications] Treats hyperpigmentation, tinea versicolor (pityriasis versicolor), and migratory wind on the head and face (erythema or pruritus). Suitable for inclusion in facial masks and bath beans (ancient cleansing cosmetics) (unnamed physician).
