The correct way to eat asparagus is to take it internally as a decoction, as a paste or in pills and proteins. Asparagus belongs to the yin tonic of the deficiency tonics, and belongs to the tuberous root of asparagus in the lily family. Asparagus is also known as Da Dang Men Root and Tian Dong. Asparagus is sweet, bitter and cold in nature. It enters the kidney meridian and lung meridian. Asparagus can be used both internally and externally. TianMenDong has the effect of clearing the lungs and lowering fire, nourishing yin and moistening dryness (nourishing yin essence and clearing heat), and is used in the treatment of sore throat, dry-heat cough, internal heat and thirst (internal heat accompanied by symptoms such as eating, drinking, and urinating), coughing with yin deficiency, heat illnesses that injure the yin, and intestinal dryness and constipation. Asparagus is cold in nature, and should be used with caution for people with cold diarrhea and wind-cold cough. Those who are allergic to asparagus should not use asparagus. If necessary, please use the medicine under the guidance of a professional Chinese medicine practitioner.
