Other herbs are likely to produce noticeable benefits after several days or weeks. For example, studies show that the benefits of palmetto berries, which are used to promote the health of the prostate, can be achieved after 12 to 18 months. Other herbs, such as those rich in antioxidants, work to improve your health without a noticeable effect.
Although, the benefits of certain herbs can be observed within a short time, others are more subtle and provide their health promoting benefits slowly. For example, we can feel the soothing effect of ginger or peppermint leaf tea almost as we drink the brew. Also, the sense of well-being resulting from the use of kava root is manifested in only a short time when using a well manufactured product.
