The effect of Xuanju capsule in a few days can not be generalized, depending on the specific condition. The main ingredients of this drug are black ant and talcum powder, which have the effect of tonifying the kidneys, dispelling wind and dampness, and relieving pain, and are mainly used for the treatment of rheumatic paralysis (i.e., the main symptoms of pain, soreness, numbness, and impaired movement in the limbs and joints caused by the evil of wind, cold, and dampness), as well as rheumatic and rheumatoid arthritis, and soreness and weakness in the waist and knees caused by liver and kidney deficiency. If the patient’s limb weakness and pain are mild and not rheumatic or rheumatoid arthritis, there may be good improvement in about 7 days with oral medication. If it is rheumatism or rheumatoid arthritis, it will take a longer period of time to adjust, and it is recommended that patients use the medicine under the guidance of a professional physician. In addition, patients should be careful not to consume cold, greasy food, and should not take other fire-relief and tonic Chinese medicines at the same time while taking Xuanju capsule.
