Men who take rape pollen for a long time can prevent prostate enlargement and can treat symptoms of lower urinary tract obstruction due to prostate enlargement, such as frequent urination, urgent urination, bifurcation of urination, waiting for urination and weakness of urination, all with varying degrees of relief. There is a clinical Chinese medicine made from rape pollen called prostate health tablets. For men over 45 years of age, all have varying degrees of prostate enlargement. This is when some patients can have symptoms, but some patients do not have any symptoms. Plant pollen has a similar effect to phytoestrogens, so it can counteract androgens and produce a mild inhibition of prostate enlargement and improve the symptoms of urinary discomfort. However, for severe prostate enlargement, there is no therapeutic effect, and it may produce some effect when taken initially, but later, as the prostate enlargement gradually increases in size, it will not help in treatment. It is recommended for younger patients that there is no need to overdose on plant pollen preparations that may affect the anti-androgenic hormone and lead to reduced sexual function. Therefore, it can be used at the discretion of those over 45 years of age and is not recommended for those under 45 years of age.
