Lümu Bark: Bitter, astringent, neutral nature, non-toxic. Burnt to ash, mainly treats blood stasis and stops bleeding. The newly formed fruit is yellowish-white, arranged in chambers like fish roe, slightly toxic; breaks blood but irritates the throat, so it should not be taken lightly. The bark can be made into ropes that do not rot even after being buried in the earth for a thousand years. Once, someone opened a tomb and obtained it; the rope had already sprouted roots. This wood is similar to Husan, Guanglang, Dongye, Pukai, Yezi, Binglang, and Duoluo in Lingnan; all are similar but have different uses. Lü is also known as Zonglü, which is the palm tree currently found in Sichuan. ○ Haiyao Yun (According to Xu Biao's "Nanzhou Ji": Grows in the valleys of Lingnan, neutral and warm; mainly treats traumatic injuries, scabies, and tinea, promotes tissue regeneration, and stops bleeding; best used burnt to ash.

Leaves pounded and applied to sores; or boiled in water to wash pus and blood. In winter, dry leaves are decocted and used for rubbing. Fang Wang's Formula: For various swellings, carbuncles that have ulcerated, and foreign bodies (thorns) stuck inside, take ten layers of Qiu leaves and apply them. Grows in valleys; also planted in gardens for timber. It shares the same root origin as Zishu but differs in the branches, similar to how Cypress leaves relate to Pine trunks. Su Jing mistakenly grouped these two woods together; this error is analyzed in the section on resolving confusion. ○ Tujing (Documented under the entry for Zibai Pi). ○ Haiyao Yun (Slightly warm; mainly promotes digestion, astringes the intestines, directs Qi downward, and treats cough due to rebellious Qi; suitable for facial powders.) ○ Shenghui Fang: Treats extreme scalp itching without pain and weeping sores; use an unspecified amount of Qiu leaves, pound and squeeze out the juice, apply to the area for immediate effect. ○ Another Formula: Treats burns that fail to heal over a long period, causing itching, pain, and yellow discharge; pound Qiu leaves or root bark into powder and apply to the sore for healing. ○ Waitai Miyao: Treats carbuncle swelling with restlessness; apply ten layers of fresh Qiu leaves, wrap with cloth/linen, adjust tightness appropriately, change three times daily to relieve pain, reduce swelling, and expel pus/blood; superior to other medicines.

Also treats ruptured carbuncles with pus ○ applying pot medicine to block the wound hole; if pain and restlessness are extreme ○ place ten layers of Qiu leaves under the pot medicine ○ wrap with cloth/linen, adjust tightness appropriately, change two to three times daily until pain and restlessness cease. This method is extremely effective, surpassing others; mainly treats post-ulceration of carbuncles/furuncles and frostbite with embedded thorns. If Qiu leaves are unavailable in winter, collect them early and moisten with salt water when needed. Selecting days is also good. Scraping the white inner bark of Qiu for use is also acceptable. ○ Another Formula: Treats angular cheilitis; paste the wet white inner bark of Qiu branches, changing several times. ○ Qianjin Yi: Treats alopecia in children; take the center of Qiu leaves, pound and squeeze juice for application. ○ Zhouhou Fang: Decoct Qiu branches into a concentrate, clean the wound hole thoroughly for great efficacy. ○ Zimu Milu: Treats hair loss on children's heads due to sores; apply juice from pounded Qiu leaves to the sore to promote hair growth, also treating tinea capitis.
