Natural remedies for overactive bladder

I have checked out this article and I noted that among the herbs that may help ease overactive bladder symptoms are the Chinese herbal blend hachi-mi-jio-gan and buchu tea.

Rehmannia, Eleuthero and Licorice for cortisol management.

I learnt from the article "Adrenal Fatigue vs. Iron Deficiency Anemia" that fatigue could be due to various factors such as low cortisol levels, low DHEA levels, anemia, and/or some other factors, and adaptogenic herbs such as rehmannia, licorice and eleuthero (Siberian ginseng) can help provide adrenal support and reduce stress. Incidentally, I found out that tankwe gin, which can be bought from Chinese TCM stores, contains rehmannia and licorice too. The information leaflet says tankwe gin is nourishing to the blood and helpful to the body building, and can mainly cure weakness, headache, dizziness and anemia, and so on.
