味苦，性平，无毒。主治霍乱、中恶（突然感受秽浊邪气所致病证）、赤白久痢，消除疳积、疥疮和癣疾，治疗牙齿虫痛，均可煎煮服用或含漱。用水浸泡后洗眼，可消除眼部红肿。其质地坚韧，可用于制作绳索，入水不腐烂。产于南海以南的山谷中。形状类似梓树的白皮（一说为桐白皮）。（今附）
臣禹锡等人谨按：日华子说：（海桐皮）性温。治疗血脉麻痹疼痛，以及目赤肿痛。煎汤外洗。
《图经》记载：海桐皮产于南海以南的山谷中，如今雷州及沿海各州郡也有出产。叶子像手掌大小，顶端分为三叉。树皮像梓树白皮那样坚硬韧性强，可以制作绳索，入水不烂。不拘泥于采药时节，随时可采集。古方中：多用于浸酒治疗风邪导致的肢体厥冷。南唐筠州刺史王绍颜撰写《续传信方》记录了这种方法：早年我在姑熟时，得了腰膝剧痛难以忍受的病症。医生认为是肾脏毒邪攻刺所致，各种药物都无法治愈。因为翻阅《传信方》发现此方有疗效，立即配制了一剂，症状立刻减轻了五分，步履变得轻盈，所以记录下来。海桐皮二两，牛膝、川芎、羌活、地骨皮、五加皮各一两，甘草半两，薏苡仁二两，生地黄十两。将前八味药材洗净焙干后细切，生地黄用芦刀切开，用一两绵纸包裹，放入无灰酒二斗中浸泡，冬季浸泡十四天，夏季浸泡七天，待药酒酿成。空腹饭后、中午及睡前各饮一杯，保持微醺状态。配制时不要随意增减药味，严禁食用毒物及发物。
海药：谨按《广志》记载：生于南海山谷中。类似桐树皮，呈黄白色，因此得名。味苦，性温，无毒。主治腰脚活动不利、顽固性痹症，腿膝疼痛，霍乱，赤白泻痢，血痢，疥癣。
大腹
性微温，无毒。主治冷热之气攻冲心腹，大肠壅滞毒邪，痰膈阻滞，反酸烧心，均与生姜、食盐同煎，加入理气药物效果更佳。产地与槟榔相似，茎、叶、根、干略有不同。产于南海各国。（今附）
《图经》内容在槟榔条目下已详述。
Haotongpi (Spatholobi Caulis)
Bitter, neutral, non-toxic. Primarily treats cholera, Zhong'e (sudden illness caused by exposure to foul pathogens), chronic dysentery with red and white discharge, eliminates malnutrition-related conditions (Ganji), scabies, and tinea; treats toothache caused by dental caries. These indications can be treated by decocting for oral administration or for holding in the mouth. Soaked in water and used to wash the eyes, it removes ocular redness. It is tough enough to be made into ropes that do not rot when submerged in water. It originates from the valleys south of the South Sea. It resembles the white bark of Catalpa trees (or Paulownia bark). (Currently appended)
Min Yuxi et al. note according to Ri Hua Zi: It is warm in nature. It treats numbness, paralysis, and pain in the blood vessels and meridians, as well as redness of the eyes. Decocted for external washing.
Tu Jing (Illustrated Classic of Materia Medica) states: Haotongpi originates from the valleys south of the South Sea; it is now also found in Leizhou and other coastal prefectures. The leaves are palm-sized with three pointed tips. The bark is hard and tough like the white bark of Catalpa, suitable for making ropes that do not decay in water. It can be harvested at any time. In ancient prescriptions: it is mostly used in wine infusion to treat wind-induced limb coldness and厥逆 (Jueyue). Wang Shaoyan, Prefect of Yunzhou during the Southern Tang Dynasty, recorded this method in his "Xu Chuanxin Fang" (Continued Records of Verified Prescriptions): In previous years, while I was in Gushu, I suffered from unbearable pain in the waist and knees. Physicians attributed it to toxic attack on the Kidneys, but no medicines worked. Upon reviewing "Chuanxin Fang," I found this verified remedy. I immediately prepared one dose, and my symptoms decreased by five parts; my gait became light. Thus, I recorded it. Haotongpi 2 liang, Niuxi (Achyranthes Bidentatae Radix), Xiongqiong (Ligusticum Chuanxiong Rhizoma), Qianghuo (Notopterygii Rhizoma et Radix), Digupi (Phellodendri Cortex), Wujia Pi (Acanthopanacis Cortex) each 1 liang, Gancao (Glycyrrhizae Radix et Rhizoma) half a liang, Yiyiren (Coicis Semen) 2 liang, Shengdihuang (Rehmanniae Radix) 10 liang. Clean and dry-bake the first eight herbs, then finely chop them. Cut the Shengdihuang with a reed knife, wrap it in 1 liang of cotton, and soak it in 2 dou of unadulterated wine. Infuse for 14 days in winter and 7 days in summer until ready. Drink one cup when fasting after meals, at noon, and before sleep, keeping oneself slightly intoxicated. Do not alter the formula during preparation; strictly avoid toxic foods and stimulating foods.
Marine Drugs: Note according to Guang Zhi: It grows in the valleys of the South Sea. It resembles paulownia bark, yellowish-white in color, hence its name. Bitter, warm, non-toxic. Primarily treats inability to move the waist and legs, stubborn bi-syndrome (painful obstruction syndrome), leg and knee pain, cholera, red and white diarrhea/dysentery, bloody dysentery, scabies, and tinea.
Dafu (Arecae Pericarpium)
Slightly warm, non-toxic. Primarily treats attacking pain in the heart and abdomen due to cold and heat qi, toxicity stagnation in the Large Intestine, phlegm obstruction, acid reflux/heartburn. Decoct together with ginger and salt; adding Qi-regulating herbs yields good results. Its origin is similar to Areca nut (Binglang); the stem, leaves, roots, and trunk differ slightly. It grows in various countries of the South Sea. (Currently appended)
The content of Tu Jing is detailed under the Binglang entry.
Sun Taizhen (Sun Simiao) says: Binglang pi (Areca nut pericarp) often hosts venomous birds (Zhen birds) roosting on these trees. It should be washed with wine first, then washed with soybean juice, before use.
