产于四川中部，皮色红且厚，气味猛烈。产自孟获城的那一株，仅存一棵，相传是诸葛亮留下的种植物，杀虫效果神奇。若活剥其皮放在蚂蚁上，蚂蚁立即死亡，如今也很少见到了。其他省份出产的称为土槿皮，皮薄且药效较差，不能混用。现在四川人常用黄葛皮来代替它，卖给其他地方。《通雅》记载：真正的川槿皮切断后，中间有丝状物，白色茸毛类似杜仲。《群芳谱》记载：川槿皮色红，气味浓郁，效力优良。
癣疮不愈：杨起《简便方》记载：对于久治不愈的癣疮，用川槿皮煎汤，将肥皂去核及内膜，浸泡在药汤中，时常擦拭；或者用汁液研磨雄黄涂抹，尤其奇妙。（又见于《不药良方》。）
顽癣多年不愈：《活人书》记载：川槿皮二钱，轻粉五分，斑蝥七个，大枫子七粒，河水、井水共一杯，煎至半杯，露天放置一夜，用笔蘸取涂抹。另一方法：川槿皮四两，轻粉、雄黄各四钱，百药煎四块，斑蝥一钱，巴豆霜半钱，大黄二两，海桐皮二两，研成粉末，用阴阳水和匀，抓破皮肤后敷上，必须等待其自然脱落才能痊愈。
荷叶癣：《活人书》记载：川槿皮切片、海桐皮、槟榔各二钱，轻粉半钱，红娘子五分，用阴阳水浸泡一两天，用鹅毛刷涂抹，如果发痒，用竹片刮破皮肤，再搽此药，夜间露天放置三个晚上，效果更好。
遍身顽癣：大枫子四十九枚，川槿皮二两，斑蝥去翅足五个，川椒一钱，轻粉二钱，杏仁三钱，海桐皮二钱，共同研末，用河水、井水各一碗，浸泡一夜，用鹅毛蘸汁涂抹。
癣疮不愈：《不药良方》记载：川槿皮煎汤，取肥皂去核及肉膜，浸泡在汤内，时常擦拭。
牛皮癣癞毛：世洪《经验集》记载：川槿皮一斤，不要见火晒燥，磨成粉末，用好烧酒十斤加榆面四两，浸泡七天为度，不时蘸酒擦拭，二三十年的顽疾，擦一年可断根。如果没有川槿，土槿也可以代替。治疗顽癣：种福堂方记载：川槿皮、海桐皮、尖槟榔、樟冰、苦参、黄柏、白芨各二钱，雷丸一钱五分，大枫子、杏仁各二粒，木鳖四个，用火酒浸泡七天，将穿山甲刮下的癣屑弄碎，用酒调和涂抹，即可痊愈。五仙散：《经验广集》记载治疗多年的顽癣、牛皮癣，神效。红粉霜五分，明矾、川槿皮、杏仁各一钱，密陀僧三钱，研成粉末，用唾液调匀涂抹，一日三次，三天全愈。

秘传雄鼠骨散：治疗牙齿脱落，可以重新生长。使用雄鼠骨一副，生打活雄鼠一只，剥去皮和内脏，用盐水浸泡一个时辰，在炭火上烤炙，肉自然脱落，取出骨头烤干，加入其他药物中，一同研成粉末。香附、白芷、川芎、桑叶晒干、地骨皮、川椒、蒲公英、青盐、川槿皮、旱莲草共同研成粉末，用来擦牙，一百天后新牙长出，固齿没有不有效的。
Produced in central Sichuan, the bark is red and thick, with a pungent odor. The single tree produced in Menghuo City is rumored to be a planting left behind by Zhuge Liang; it possesses miraculous insecticidal properties. If its fresh bark is placed on ants, they die immediately, but such specimens are now rare. Those produced in other provinces are called *Tu Jin Pi* (Bark of *Hibiscus tiliaceus*), which are thin and inferior in efficacy, and must not be mixed or used interchangeably. Currently, people in Sichuan often substitute it with *Huang Ge Pi* (Bark of *Ficus virens*) to sell elsewhere. *Tong Ya* records: True *Chuan Jin Pi* (Bark of *Hibiscus mutabilis*), when cut, contains fibrous strands inside, with white down similar to *Du Zhong* (Eucommia Bark). *Qun Fang Pu* records: *Chuan Jin Pi* is red in color, with a rich odor and potent efficacy.
For stubborn tinea (ringworm) that does not heal: Yang Qi's *Jian Bian Fang* (Simple and Convenient Prescriptions) states: For persistent tinea, decoct *Chuan Jin Pi* (Bark of *Hibiscus mutabilis*). Remove the core and inner membrane from soap, soak it in the decoction, and apply frequently. Alternatively, grind *Xiong Huang* (Realgar) into juice and apply; this is particularly effective. (Also seen in *Bu Yao Liang Fang*.)
Stubborn tinea persisting for many years: *Huo Ren Shu* (Book of Living People) states: Use 2 qian of *Chuan Jin Pi*, 5 fen of *Qing Fen* (Calomel), 7 *Ban Mao* (Blister Beetle), and 7 *Da Feng Zi* (Big Cardamom Seed). Decoct with one cup of river and well water until half remains. Expose overnight, then apply with a brush. Another prescription: 4 liang of *Chuan Jin Pi*, 4 qian each of *Qing Fen* and *Xiong Huang*, 4 pieces of *Bai Yao Jian* (Myrobalan Pill Base), 1 qian of *Ban Mao*, 0.5 qian of *Ba Shuang* (Croton Seed Frost/Resin), 2 liang of *Da Huang* (Rhubarb Root), and 2 liang of *Hai Tong Pi* (Palm Wood Bark). Grind into powder, mix with *Yin Yang Shui* (water boiled and cooled, or mixed spring and rain water), scratch the skin until broken, and apply. Healing occurs only after the scabs fall off naturally.
Lotus-leaf shaped tinea: *Huo Ren Shu* states: Slice *Chuan Jin Pi*, *Hai Tong Pi*, and *Bing Lang* (Areca Nut) at 2 qian each; add 0.5 qian of *Qing Fen* and 5 fen of *Hong Niang Zi* (Red Ladybug). Soak in *Yin Yang Shui* for one to two days. Apply with a goose feather. If itching occurs, scrape the skin with a bamboo splinter before applying the medicine. Expose overnight for three nights for better effect.
Generalized stubborn tinea: 49 *Da Feng Zi* seeds, 2 liang of *Chuan Jin Pi*, 5 *Ban Mao* (de-winged and de-footed), 1 qian of *Chuan Jiao* (Sichuan Pepper), 2 qian of *Qing Fen*, 3 qian of *Xing Ren* (Apricot Seed), and 2 qian of *Hai Tong Pi*. Grind all into powder. Soak overnight in one bowl each of river and well water. Apply the juice with a goose feather.
Persistent tinea: *Bu Yao Liang Fang* states: Decoct *Chuan Jin Pi*. Remove the core and fleshy membrane from soap, soak in the decoction, and apply frequently.
Psoriasis-like hairy tinea: Shi Hong's *Jing Yan Ji* (Collection of Experienced Formulas) states: Take 1 jin of *Chuan Jin Pi*, dry it without fire exposure, and grind into powder. Add 10 jin of good distilled liquor and 4 liang of elm flour. Soak for seven days. Dip and rub frequently. Even cases lasting twenty to thirty years can be cured in one year. If *Chuan Jin Pi* is unavailable, *Tu Jin Pi* may serve as a substitute. Treating stubborn tinea: *Zhong Fu Tang* formula states: Use 2 qian each of *Chuan Jin Pi*, *Hai Tong Pi*, pointed *Bing Lang*, *Zhang Bing* (Camphor Ice), *Ku Shen* (Sophora Root), *Huang Bo* (Phellodendron Bark), and *Bai Ji* (Bletilla Tuber); 1.5 qian of *Lei Wan* (Omphalia Powder); 2 grains each of *Da Feng Zi* and *Xing Ren*; and 4 *Mu Bie* (Monkey Head Fruit). Soak in fiery wine for seven days. Scrape scales from *Chuan Shan Jia* (Pangolin Scales), crush them slightly, mix with wine, and apply. It will heal. *Wu Xian San* (Five Immortals Powder): From *Jing Yan Guang Ji*, highly effective for long-standing stubborn tinea and psoriasis. Mix 5 fen of *Hong Fen Shuang* (Red Lead Powder), 1 qian each of *Ming Fan* (Alum), *Chuan Jin Pi*, and *Xing Ren*; 3 qian of *Mi Tuo Seng* (Litharge). Grind into powder, mix with saliva, and apply three times daily. Complete healing occurs in three days.
Acne: Sun Taishi's formula states: Use 1 liang of *Chuan Jin Pi*, 2 liang of *Liu Huang* (Sulfur), 2 liang of *Xing Ren* (de-skinned and de-husked), 2 qian of *Qing Fen*, 5 qian of *Zhang Nao* (Camphor), and a small amount of *She Xiang* (Musk). Grind into powder, mix with egg white. Wash in the morning and apply at night.
Secretly Transmitted Male Rat Bone Powder: Treats tooth loss, promoting regrowth. Take one male rat bone. Strike a live male rat to death, remove skin and viscera, soak in salt water for one shichen (two hours), roast over charcoal fire until meat falls off. Dry the bone, add to other medicines, and grind into powder. Mix with equal parts of *Xiang Fu* (Cyperus Rhizome), *Bai Zhi* (Angelica Dahurica), *Chuan Xiong* (Sichuan Lovage Rhizome), dried *Sang Ye* (Mulberry Leaf), *Di Gu Pi* (Lycium Bark), *Chuan Jiao*, *Pu Gong Ying* (Dandelion), *Qing Yan* (Rock Salt), *Chuan Jin Pi*, and *Han Lian Cao* (Eclipta Herb). Grind together into powder. Rub teeth with this powder; new teeth will emerge within one hundred days. Effective for strengthening teeth.
