Artificially grown asparagus also has medicinal properties. Now the number of wild asparagus is not much, far from meeting the demand for people to use, so it must rely on artificially cultivated asparagus, in order to provide a sufficient source of drugs. The effect of artificially cultivated tianma and wild tianma is basically the same. Tianma is a kind of traditional Chinese medicine, for the orchid plant Tianma dried tubers. Its flavor is sweet, neutral, attributed to the liver meridian, has the effect of restraining wind and stopping spasm, calming the liver yang, expelling wind and clearing the channels (expelling wind evil, dredging the meridians). It is mainly used for treating headache and dizziness caused by pediatric convulsions (pediatric diseases mainly manifested by dizziness, convulsions and convulsions), epileptic convulsions, tetanus, hyperactivity of liver yang (liver yang is over-exuberant, which causes dizziness, dizziness, headache and other symptoms), numbness and insensitivity of limbs, unfavorable movement of hands and feet, and rheumatic paralysis. Adverse effects of the drug are occasional allergic reactions occurring in some people after the use of Tianma and Tianma preparations. Due to yin deficiency and fire exuberance (deficiency of yin essence in the body, the emergence of hyperactive deficiency fire), blood deficiency and blood dryness, solid heat within the internal movement of the liver wind is not suitable for those who take a single medicine. Tianma should be used under the guidance of a professional Chinese medicine practitioner, and should not be used blindly on its own to avoid adverse reactions.
