A scientific publication likely written in the late 18th century. The text delves into the investigation of the properties and effects of foreign teas, particularly those sourced from India and China, arguing for their harmful consequences on human health, especially related to the nervous system. Smith seeks to provide evidence against the use of foreign teas and explores alternative beverages deemed more beneficial. At the start of the treatise, the author emphasizes the importance of reassessing widely consumed foreign teas, asserting that they are not only inadequate as a nourishing beverage but also a potential source of various health ailments. The text discusses the composition, preparation, and effects of these teas, illustrating their damaging impact on the body. Smith sets the stage for a detailed examination of the specific ailments caused by these teas and offers remedies, including the promotion of a tea developed by Dr. Solander, which he argues provides an invigorating and restorative alternative to the detrimental effects of traditional Indian teas.
