Fenghuangyi has the effects of nourishing yin and clearing the lungs, healing sores and promoting tissue regeneration, mending bones and treating injuries, and improving eyesight by resolving opacity in the eyes. It is mainly used to treat symptoms such as cough and expectoration, sore throat, tidal fever and night sweats, and hoarseness caused by lung yin deficiency, helping to nourish yin, clear heat, and soothe the throat. Fenghuangyi, with a neutral nature, can also improve symptoms such as sores in the mouth and tongue, redness, swelling, and pain, and ulcers caused by heat-toxin accumulation, exhibiting the effect of healing sores and promoting tissue regeneration. Fenghuangyi also has the function of promoting blood circulation to remove blood stasis and can be used to treat traumatic fractures, redness, swelling, and pain caused by injuries from falls and impacts, aiding in mending bones and treating injuries. If patients have eye diseases, they can also take Fenghuangyi as prescribed by their doctor, which helps to improve symptoms such as opacity in the eyes and swelling and pain in the eyelids. If patients are allergic to Fenghuangyi, it may cause skin itchiness, redness, rash, and other allergic reactions after ingestion.
