The Many Uses of Bletilla: Both Medicinal and Ornamental Value

Bletilla (Bletilla striata) is a perennial herb in the genus Bletilla of the orchid family, also known as baiji and lianjicao. It is mainly found on shady hillsides in southern China. Its underground tubers are irregularly flattened and round, rich in sticky mucilage, and it is an important member of traditional Chinese medicine. It can be used as medicine and also has a certain ornamental value.

In traditional Chinese medicine, the tuber of Bletilla is used as medicine. It is slightly cold in nature with a bitter and astringent taste, and is often classified as an astringent hemostatic. It is mostly used for coughing up blood, vomiting blood, and bleeding from trauma, and is also considered helpful for reducing swelling and promoting tissue regeneration. In practice, it is often combined with other medicinal materials, and the specific method and dosage should be determined by a professional physician according to individual circumstances.

Besides its medicinal use, the ornamental value of Bletilla has also gained increasing attention. Its flowers are mostly purplish red or pale pink and bloom in clusters, making it suitable for planting at forest edges, in courtyards, or as ground cover, adding color to damp, shady environments. In recent years, artificial cultivation has gradually expanded, which both meets the demand of the medicinal materials market and helps protect wild resources.

In addition, the mucilage extracted from Bletilla tubers is quite sticky and has traditionally been used as a natural adhesive material; today its applications in daily chemicals, food, and other fields are also being continuously explored. It should be noted that Bletilla is, after all, a medicinal material, so a physician should be consulted before household use. Pregnant women and those with special constitutions should be especially cautious, and it should never be taken blindly on one's own.
