榈木皮：味苦、涩，性平，无毒。烧成灰后，主治破血和止血。其果实初生时呈黄白色，形状像鱼子一样聚集成房状。有小毒。能破血，但会刺激人的咽喉，不可轻易服用。树皮可制作成绳索，埋入土中千年不腐烂。过去有人挖掘古墓得到它，发现已经生根。这种树木与岭南地区的虎散、桄榔、冬叶、蒲葵、椰子、槟榔、多罗等相似，但各有所用。棕榈又名榈木，即现在四川地区的棕榈树。
海药记载说：谨按徐表《南州记》记载：生长在岭南的山谷中。性平、温。主治金疮（金属利器造成的创伤）疥癣，生肌止血，都适宜烧成灰使用。其果实黄白色，有大毒，不适合服用。
楸木皮：味苦，性小寒，无毒。主治呕吐逆气，杀灭三虫及皮肤寄生虫。煎制成膏，粘稠地敷在恶疮、疽、痈肿、疳疮、野鸡病上。能去除脓血，促进肌肤生长，强健筋骨。叶子捣碎后敷在疮肿上。也可以煮汤，清洗脓血。冬天取干叶煮汤揉搓使用。《范汪方》中治疗各种肿痈溃烂，以及体内有刺拔不出来的情况。取十层楸叶贴敷。生长在山谷间。也种植在园林中，作为木材使用，它与梓树本源相同但末梢不同，就像柏叶与松身一样，苏敬将这两种树混为一谈是错误的。详细分析在“解纷”条中已有说明。图经详细记载在“梓白皮”条下。
海药记载说：性微温。主治消食，涩肠，降气及上气咳嗽，都适宜加入面药中使用。圣惠方：治疗头部极度瘙痒，不痛，长出疮疡。用楸叶不限多少，少量捣碎绞汁涂抹。又一方：治疗灸疮长时间不好，痒痛，流出黄水。用楸叶或根皮，捣碎过筛成粉末，敷在疮上，即可痊愈。外台秘要治疗痈肿烦闷困倦。取十层生楸叶贴敷，用布帛包裹，松紧适度，每天更换三次。止痛消肿，消化脓血，效果极好，胜过其他药物。冬天用预先收存的干叶，临时用盐水润湿使用。又主治患痈疮破溃，排尽脓液后，用瓮药塞住疮孔，若疮痛烦闷困倦至极的方子：取十层楸叶去掉瓮药覆盖其上，用布帛包裹，松紧适度，每天多次更换。疼痛烦闷即止。此法非常好，胜过其他方法。主治痈疽溃烂后及冻疮，有刺拔不出来，效果很好。冬天没有楸叶时，应当提前收存，临时用盐水润湿使用，选择吉日也好，薄削楸白皮使用也可以。又一方：治疗口吻疮。用楸枝皮白色部分，湿润粘贴，多次更换。千金翼治疗小儿头发不生。取楸叶中心部分，捣碎绞汁涂抹。肘后备急方洗净疮子孔中，效果显著。子母秘录：治疗小儿头上疮，头发不生。楸叶捣汁，涂在疮上，头发即生，兼治白秃。
**Bark of Trachycarpus fortunei (Lümu Pi):** Bitter, astringent, neutral in nature, non-toxic. When burned to ash, it treats blood stasis and stops bleeding. The fruit is initially yellowish-white, clustered like fish roe. It has slight toxicity. It breaks blood stasis 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 soil for a thousand years. In the past, someone excavating a tomb found it already rooted. This tree resembles those in Lingnan such as *Hu San*, *Guanglang*, *Dongye*, *Pukui* (Licuala palm), *Yezhi* (Coconut), *Binglang* (Areca nut), and *Duoluo*, each having its own uses. Lü is another name for Zonglü, which is the palm tree currently found in Sichuan.
According to *Haiyao*: As recorded by Xu Biao in *Nanzhou Ji*: Grows in the valleys of southern mountains. Neutral, warm. Treats metal wounds (*Jinchuang*), scabies, and tinea; promotes tissue regeneration and stops bleeding; best used when burned to ash. Its fruit is yellowish-white, highly toxic, and unsuitable for ingestion.
**Bark of Catalpa ovata (Qiumu Pi):** Bitter, slightly cold, non-toxic. Treats vomiting and rebellious qi, kills three types of parasites and skin parasites. Decocted into a paste, applied viscously to malignant sores, carbuncles, abscesses, ulcers, and "wild chicken disease." Removes pus and blood, promotes skin growth, and strengthens sinews and bones. Leaves, crushed and applied to sores and swelling. Can also be boiled into a decoction to wash away pus and blood. In winter, dry leaves are boiled and rubbed for use. *Fang Wang Fang*: For various swellings and carbuncles that have ulcerated, or when foreign bodies like thorns remain inside. Apply ten layers of Catalpa leaves. Grows in mountain valleys. Also planted in gardens for timber. Its root origin is the same as *Zishu* (Catalpa bungei) but its branches differ, similar to how cypress leaves differ from pine trunks. Su Jing mistakenly treated them as one species. Detailed analysis is in the section on "Resolving Confusion." *Tujing* details are under the entry for "White Bark of Catalpa bungei."
According to *Haiyao*: Slightly warm. Treats digestion, astringes intestines, directs rebellious qi downward, and treats cough with upward rushing qi; suitable for inclusion in facial preparations. *Shenghui Fang*: Treats extreme scalp itching without pain, resulting in sores. Use an unspecified amount of Catalpa leaves, crush slightly, extract juice, and apply. Another prescription: Treats moxibustion sores that fail to heal for a long time, causing itching, pain, and yellow discharge. Use Catalpa leaves or root bark, crush and sieve into powder, and apply to the sore for cure. *Waitai Miyao*: Treats abscess swelling with distress and fatigue. Apply ten layers of fresh Catalpa leaves, wrap with cloth/silk, adjust tightness appropriately, change three times daily. Relieves pain, reduces swelling, digests pus and blood; effect is excellent, surpassing other medicines. In winter, use pre-stored dry leaves, moisten with salt water before use. Also treats ruptured abscesses where pus has been drained, using urn medicine to plug the wound; if severe pain and distress occur: Remove the urn medicine, cover with ten layers of Catalpa leaves, wrap with cloth/silk, adjust tightness, change multiple times daily. Pain and distress cease immediately. This method is extremely effective, surpassing others. Treats post-ulceration of carbuncles/furuncles and frostbite with embedded thorns; very effective. If no fresh leaves in winter, store early, moisten with salt water before use, or choose an auspicious day; thin slices of white bark can also be used. Another prescription: Treats angular cheilitis. Use the white inner bark of Catalpa branches, apply wet, change frequently. *Qianjin Yi Fang*: Treats alopecia in children. Take the center of Catalpa leaves, crush, extract juice, and apply. *Zhouhou Beiji Fang*: Clean the pustule holes thoroughly; highly effective. *Zimu Milu*: Treats scalp sores in children preventing hair growth. Crush Catalpa leaves, extract juice, apply to sores; hair will grow, also treating tinea capitis (white ringworm).
