There is no clear rule on how long it is generally recommended to take Ulin Capsules, which needs to be decided according to the patient’s physique, condition and other factors. However, if the symptoms are not relieved after 7 days of taking the medicine, you should go to the hospital for consultation. Wu Ling Capsule has the effect of tonifying the kidney and brain, nourishing the heart and tranquilizing the mind (stabilizing the mind by nourishing the heart). It is used for insomnia, forgetfulness, palpitation (rapid heartbeat, often accompanied by panic), heartburn, fatigue (mental exhaustion, physical weakness), lumbar and knee weakness (a feeling of soreness and weakness in the lumbar and knee regions) caused by heart and kidney dysfunction (heart fire, kidney yin deficiency, and dysfunction in the physiological functions of the heart and kidneys).

If you need to use Wu Ling Capsules, you must use it under professional medical supervision.
