《纲目拾遗》：“雪茶，出云南永善县。其地高山积雪，入夏不消，雪中生者，本非茶类，乃天生一种草芽。土人采得炒焙，以其似茶，故名。其色白，故曰雪茶。己亥腊，过余杭，往访刘挹清少府，啜雪茶。云带自云南，茶片皆作筒子，如蜜筒菊蕊瓣样。询所主治，因言此茶大能暖胃，凡严寒冰冻时，啜一盏，满腹如火，若患痨损及失血过多之人，腹胃必寒，最忌食茶，惟此茶不忌。乃相与烹瀹食之，果入腹温暖，味亦苦冽香美，较他茶更厚。”临床应用 相关配伍
"Collection of Forgotten Notes on the Essentials of Medicine": "Snow Tea, originating from Yongshan County in Yunnan Province. The region is covered in snow on high mountains, which does not melt even in summer. The plants growing in the snow are not originally tea plants, but a type of grass sprout naturally born from the heavens. The local people pick and roast them, and because they resemble tea, they are named as such. The color is white, hence the name Snow Tea. In the winter of the year Ji Hai, passing through Yuhang, I went to visit the Imperial Censor Liu Yiqing and tasted Snow Tea. It was brought from Yunnan, and the tea leaves were all rolled into small tubes, resembling the petals of chrysanthemum buds. Inquiring about its main therapeutic effects, it was said that this tea has a strong warming effect on the stomach. When experiencing severe cold or frost, drinking a cup warms the stomach like fire. For those suffering from tuberculosis, excessive blood loss, or cold stomach due to other reasons, it is best to avoid drinking tea, except for this Snow Tea. We then cooked and consumed it together, and indeed, it warmed the stomach upon ingestion. Its taste is bitter, refreshing, and fragrant, thicker compared to other teas."
