Ethnobotanical survey of cooling herbal drinks from southern China.

Liu Y, Ahmed S, Long C - J Ethnobiol Ethnomed (2013)

Bottom Line: However, there is a knowledge gap on the plant species used and commercialized for cooling herbal drinks in southern China and their associated ethnobotanical use, habitat and conservation status.This is the first study to document plant species used and commercialized as liáng chá in southern China's Lingnan region and associated ethnomedical function, preparation methods, habitat and conservation status.Future research on safety and efficacy of herbal drinks as well as ecological and cultural conservation efforts are needed for the sustainable growth of China's botanical industry.

ABSTRACT

Background: Liáng chá ("cooling tea", "herbal tea" or "cool tisane" in Chinese) are herbal drinks widely produced in southern China and consumed by billions of people worldwide to prevent and treat internal heat as well as a range of associated health conditions. Globalization and renewed interest in botanical remedies has attracted growing attention in cooling herbal drinks by industry, scientists and consumers. However, there is a knowledge gap on the plant species used and commercialized for cooling herbal drinks in southern China and their associated ethnobotanical use, habitat and conservation status. This is the first study to document plant species used and commercialized as liáng chá in southern China's Lingnan region and associated ethnomedical function, preparation methods, habitat and conservation status.

Methods: Three hundred market surveys were conducted between 2010-2012 in the largest herbal drink producing region of China to record plants used for liáng chá and to document knowledge on their medicinal function, habitat and conservation status. Product samples and voucher specimens were collected for taxonomic identification.

Results: All informants harvest and cultivate plants for preparing herbal drinks for their medicinal, cultural and economic values. A total of 222 ethnotaxa corresponded to 238 botanical taxa (species, varieties or subspecies) belonging to 86 families and 209 genera were recorded as liáng chá to treat health conditions in the study area. Recorded remedies consisted of one or several plant species to treat conditions classified into 27 major health conditions with clearing internal heat being the most common medicinal function. The habitat types of plants documented for use as liáng chá include 112 wild harvested species, 51 species that are either wild harvested or cultivated, 57 cultivated species, and 2 naturalized species. According to China's Red List and CITES on conservation status, one of these species is endangered, one species is critically endangered, eight species are vulnerable, one is listed in CITES II, three are listed in Regional Red Data Book and the remaining 224 species are in the least concerned conservation category.

Conclusions: The liáng chá industry of southern China reflects the plant species richness and cultural diversity of the region. Future research on safety and efficacy of herbal drinks as well as ecological and cultural conservation efforts are needed for the sustainable growth of China's botanical industry.

Mentions: Liáng chá refers to “cooling tea” or herbal tisanes/teas produced from water infusions of a range of plant species other than the caffeine-containing tea plant (Camellia sinensis; Theaceae). Plant material may consist of fresh or dried leaves, fruit, flowers, pollen, nuts, barks, seeds and roots from a single species or multiple species. The practice of drinking liáng chá is an ancient custom regarded to have originated from the Lingnan region of southern China over 2,000 years ago. Lingnan is the tropical and subtropical region south of China’s Nanling Mountains that covers all or part of Guangdong, Guangxi, Hainan, Hong Kong, Macau, Hunan and Jiangxi provinces (Figure 1). This region is notable for its rich biodiversity and cultural practices.
