Note: Yunnan also produces a kind of nard, which is of the same genus, Nardostachys grandiflora. The difference between it and nard is that the plant is shorter, with flower stems generally 15 to 20 cm high; the leaves are wider, oblanceolate or elliptic-lanceolate; the flowers are larger; the calyx is also large, and the ovary is hairy. The shape of the crude drug is similar to the above species, but it is thicker, about 13 cm long and 1.5 cm in diameter. There are many basal leaf stumps, which are mostly fibrous and gray-brown. The rhizome is longer and quadrangular, and many of them are connected to a main root, with a weaker aroma. The quality is poor, so it is not widely used.

The above is some introduction about the effects of nard. Many Chinese herbal medicines in our lives have different medicinal properties, so we must have a general understanding of some of the medicinal properties of Chinese herbal medicines and their consumption taboos, so as to avoid causing some unnecessary harm and enable Chinese medicine to exert its best effect and help us regulate our bodies.
