For herbal formulas that are designed for addressing a health issue before it manifests, it’s best to take them regularly for two to three months. For herbal formulas that are designed to restore balance it’s best to take them until the imbalance has been addressed. Once balance is restored, you can continue for at least two weeks longer to be sure the body has adjusted to the new state of balance. For detoxifying herbal formulas, it’s best to use them according to the guidelines given. For certain ongoing issues, it may be helpful to take the supplement on a regular basis to enjoy balance.
