产自徽州，当地人在二三月采茶时，兼采十大功劳的叶子，俗名老鼠刺，这种叶子叫苦丁，混合均匀后一同炒制烘焙成茶，卖给尼姑庵，再转售给富家妇女，据说妇女服用后终身不孕，是断绝生育的第一妙药，每斤售价八钱银子。味道极甘苦且香气浓郁，兼能驱风活血。绝育效果如神。
范成大（石湖居士）文集记载：修江出产栾茶，其实是石楠树的叶子。毛文锡《茶谱》说：湖南人四月采集杨洞汁做饭，则必须采集石楠叶来治疗头风病。
《宦游笔记》记载：山东蒙山位于蒙阴县城南三十里处，高约二十里，周围约三百余里，出产一种叫云芝茶的茶，当地人将其在市场上出售称为蒙山茶，但这绝非真正的茶类，而是生长在山石中的石衣，属于苔藓一类，当地人捧取它冲泡，冒充茗茶。《五杂俎》记载：蒙山在四川雅州，其中峰顶极其险恶污秽，是毒蛇猛虎野狼栖息的地方，得到那里的茶，可以消除各种疾病。如今山东人用蒙阴山下的石衣当作茶来替代，这是错误的。然而蒙阴茶性质寒冷，可以治疗胃热之病，性寒，能消除积滞。《本草纲目》中有石蕊，说其性温，未提及能消积滞。
产自粤西，似红花嫩苗制成，当地人制作用来赠送客人。宋代邹道乡有诗云：消除膈间滞气和宿食，辟除烟岚瘴气。
产自东莞，以芝麻薯油混合茶汁煎煮而成。去除风湿，破除食积，治疗饥饿（应昌按：乌药茶与前文提到的研茶制造方法和主治功效都相同，不知是同一物还是两种不同之物）。
《四川通志》记载：泸州出产，通称为泸茶。味道辛烈，性质热，饮用它可以治疗风疾。
《福建志》记载：产自福宁府。治疗瘟疫。
《茶谱》记载：鄂州乐山出产的茶，颜色黑如韭菜。又说：产自鄂州东山，名叫东山茶，颜色黑如韭菜，性质与韭菜相反。
Produced in Huizhou, during the tea picking season in the second and third lunar months, locals also pick the leaves of *Mahonia fortunei* (Daduli Gong), commonly known as "Lao Shu Ci" (Rat Thorn). These leaves are called "Ku Ding" (Bitter Bulb) and are mixed evenly with tea leaves, then stir-fried and baked together to make tea. It is sold to nunneries and resold to wealthy women, who claim that consuming it renders them permanently infertile, making it the premier miraculous remedy for contraception. The price is eight mace of silver per jin. It has a taste that is extremely sweet and bitter, yet highly fragrant, and can simultaneously dispel wind and invigorate blood. Its ability to prevent pregnancy is miraculous.
Fan Chengda (Shihu Jushi) in his collected works records: Luancha produced in Xiujiang is actually the leaf of *Pieris sinensis*. Mao Wenxi's *Cha Pu* (Tea Classic) states: In Hunan, people collect Yangdong juice in the fourth month to cook rice; they must also collect *Pieris sinensis* leaves to treat cephalalgia caused by wind.
*Huanyou Biji* (Notes on Traveling for Official Duties) records: Mount Meng in Shandong is located thirty li south of Mengyin County, standing approximately twenty li high, with a circumference of over three hundred li. It produces a tea called Yunzhi Cha. Locals sell it in the market as Mengshan Cha, but it is absolutely not a true tea species. It is "Shiyi" (Stone Lichen) growing among mountain rocks, belonging to the moss family. Locals scoop it up and brew it, passing it off as fine tea. *Wuzazu* (Miscellaneous Stuffs from Five Regions) records: Mount Meng in Ya Zhou, Sichuan, has a peak that is particularly dangerous and filthy, inhabited by snakes, tigers, and wild wolves. Tea obtained there can eliminate various diseases. Today, people in Shandong use the stone lichen from the foot of Mount Yin as a substitute for tea, which is incorrect. However, Mengyin tea is cold in nature, capable of treating stomach heat conditions; being cold, it can resolve food stagnation. *Bencao Gangmu* mentions Shilui, stating it is warm in nature, without mentioning its ability to resolve stagnation.
Produced in Western Guangdong, made from tender shoots resembling those of *Carthamus tinctorius* (Safflower). Locals prepare it to gift to guests. Zou Daoxiang of the Song Dynasty wrote a poem: [It] resolves diaphragmatic stagnation and retained food, and repels miasma and pestilential qi.
Produced in Dongguan, brewed by mixing sesame oil or potato starch oil with tea juice. It dispels wind-dampness, breaks down food accumulation, and alleviates hunger. (Ying Chang notes: The manufacturing methods and therapeutic indications of Wuyao Cha and the previously mentioned Yancha are identical; it is unknown whether they are the same substance or two different ones.)
*Sichuan Tongzhi* (General Gazetteer of Sichuan) records: Produced in Luzhou, generally referred to as Lucha. It tastes pungent and is hot in nature; drinking it can treat wind disorders.
*Min Zhi* (Fujian Gazetteer) records: Produced in Fning Prefecture. It treats epidemic febrile diseases.
*Cha Pu* (Tea Classic) records: Tea produced at Le Shan in E Zhou is black like leeks. It further states: Produced at Dong Shan in E Zhou, named Dongshan Cha, black in color like leeks, but its nature is opposite to that of leeks.
