According to the general principles of phytotherapy, continuous administration of any one herbal remedy lasting more than 3-4 weeks, with some exceptions, is undesirable.
The specified period is sufficient for the course. After a break (at least 1 week), one can repeat the course, followed by additional preventive or anti-relapse courses 1-2 times a year for several years. To ensure the principle of continuity, it is necessary to develop 2-4 herbal collections, different in composition, but of the similar therapeutic activity. Alternating the use of such mixtures, side effects, overdose and other side effects are avoided.
