Astragalus is both the common name of one of the most widely used herbs in Chinese medicine, as well as the name of the plant group from which it originates. Astragalus membranaceus is known in China as âhuang-qiâ which means âyellow leaderâ. âHuangâ means âyellow,â referring to the yellow interior of the root. â Qiâ means âleader,â referring to this herb as one of the superior âtonicsâ in Chinese medicine. Another plant Astragalus membranaceus var. mongholicus (A. mongholicus) is also used as huang-qi. Regionally in China, several local species are considered acceptable substitutes for the officially listed source plants.
Written By: American Sign Language (ASL), visual-gestural language used by most of the deaf community in the United States and Canada. ASL is a natural language with a structure quite different from spoken English. It is not a manual-gestural representation of spoken English, nor is it pantomime. Instead, ASL is a full language, with all of the properties of spoken natural languages, but one that has developed independently of and differently from English. The role of ASL in the education of deaf students has been characterized by conflict and controversy.
