The main ingredient in Paulownia is finasteride, an anti-androgen treatment that selectively blocks the action of androgens to treat prostate enlargement. The actual fact is that you can find a lot of people who are not able to get a good deal on a lot of things. This is why you need to take a long-term medication to treat prostate hyperplasia. The only thing that can change the process of prostate enlargement is finasteride. There are large experimental studies abroad that confirm that older men with prostate enlargement have no significant side effects after five years of long-term treatment with Paulownia. However, the problem to be noted is that Borealis can affect the concentration of prostate-specific antigen, or PSA, in the blood, so it is important to be aware of this during screening for prostate cancer.
