The corpus cavernosum, also known as the corpus cavernosum muscle, is a muscle group located on the penis that plays an erectile role. If there is an injury to the corpus cavernosum, it is usually caused by factors such as trauma or excessive masturbation. This condition can be improved by a variety of methods. It can be treated by drugs that invigorate blood circulation, such as the application of Panax ginseng tablets, or by local physiotherapy and other methods. If it is caused by excessive masturbation, you should also pay attention to abstain from masturbation and avoid bad stimulation. You can take some Chinese medicines orally to improve the symptoms, such as Liu Wei Di Huang Wan and Fu Fang Xuan Fructus Capsules. If this condition has damaged the nerves in the penis area, you also need to use some nerve-nourishing drugs to treat it, such as vitamin B and vitamin B12.
