The word "patent" is generally used to refer to formulated pills or tablets. In addition to the classic formulas, many new formulas have been developed over the years. It is a convenient way to take the herbs since the sometimes unpleasant taste of herbal tea can largely be avoided. It is also often the most economical form of herbal remedies. The pill form is especially beneficial for chronic conditions. And with new technologies, more concentrated patents have become available so fewer pills need be taken.
