Tianma is the rhizome of an orchid, and winter and spring are the best time to dig. Among them, the quality of tianma dug in winter is better, known as winter hemp, while the quality of tianma dug in spring is slightly inferior, known as spring hemp. Tianma has medicinal effects such as dispelling wind-dampness, relieving pain, and promoting circulation of Qi and blood. Common applications include relieving symptoms such as headache, dizziness and numbness of limbs. Making soup is a common cooking method to dissolve the medicinal components of Tianma in the soup, making it easier to be absorbed by the body. When the number of people making soup is 5, it is appropriate to put 30-45 grams of fresh asparagus. This range can be adjusted according to personal taste and needs. If you want the soup to have a stronger flavor, you can put in more asparagus; if you want a lighter taste, you can reduce the amount of asparagus in moderation.
