Myocarditis belongs to the category of chest paralysis (chest tightness and pain), heart pain, palpitation (rapid heartbeat, often accompanied by panic) and other diseases in traditional Chinese medicine. Rejuvenate Spleen Capsules may improve the symptoms of palpitation disease with deficiency of qi and blood and cardiac qi to a certain extent, but it is more difficult to achieve a cure for myocarditis. The main effects of Rejuvenate Spleen Capsules are to benefit qi and strengthen the spleen (regulating the qi of the spleen and stomach), nourish blood and tranquilize the mind (stabilizing the mind and soothing the emotions by nourishing the blood), and are used for deficiency of the heart and the spleen (weakness of the heart and the spleen), shortness of qi and palpitation, insomnia, dizziness, tiredness of the limbs, and loss of appetite. Adverse reactions to this product have been reported in cases causing gastrointestinal discomfort and skin rash. Avoid indigestible food. Not recommended for patients with cold and fever. It is not suitable for those with internal heat manifestations such as thirst, yellow urine and constipation. It is contraindicated for those who are allergic to the product, and should be used with caution by those with allergies. However, because myocarditis is a more critical condition, which may lead to heart failure and sudden death in severe cases, the efficacy of simple treatment with proprietary Chinese medicines is limited, and it is difficult to achieve a complete cure for myocarditis. Therefore, the treatment of categorization capsule can generally be used as an auxiliary means, and can not be used as the main means of treatment of myocarditis. It is recommended that people with myocarditis consult regular hospitals in a timely manner to be diagnosed and treated by professional doctors.
