There is some proof that the herbal supplement ginkgo biloba helps lessen fluid retention and swelling brought on by hydrocele. To be effective, many Herbal Supplement for Hydrocele must be taken over a lengthy period of time. In contrast, evidence indicates that ginkgo biloba may be beneficial after just three months of usage (Journal of Urology). You should start taking 300mg once day, or as your doctor directs, for the optimum benefits.
