Herbal Rating Standards
According to Alan Keith Tillotson Herbal Ratings color-codes ratings guidelines are:
You’ve said that some herbs are very safe for long-term use, but what about all the others?
Yellow Standard
Yellow Standard: There are other herbs that, although extremely beneficial and important in the treatment of certain conditions, have a limited range of action or must be used with caution. Mild or moderate diuretics, for example, may be very useful for a few weeks or months, but I do not see the sense in taking them for long periods of time. I classify these herbs as Yellow standard.
