Can You Drink Different Herbal Teas In a Day?

Herbal Teas

A common concern among those interested in natural or herbal remedies is, “Is it safe to drink more than one or multiple types of herbal tea per day?” The answer to that question is not a simple yes or no, as some types of herbs interact with one another and dosage also plays an important role. When combining various types of tea in a 24 hour period, keep the following in mind:

Mixing Herbs

Alternative medicine routinely involves mixing a wide range of herbs to promote one’s health, however this is typically done by an expert who has knowledge of dosage and interactions that may occur. TCM or Traditional Chinese Medicine often involves the use of a wide range of herbal mixtures to complement one another, providing the greatest positive effect for one’s health. However, the average tea lover does not have such an extensive knowledge of herbs and possible health risks. Before consuming more than one type of tea:

  • Always adhere to the recommended dosage
  • Cross check for any potential interactions (other herbs, pharmaceuticals and medical conditions)
  • Try one tea combination at a time and add more slowly

Some Known Interactions

While it’s typically safe to combine most herbs, including a wide range of teas and infusions, some known reactions to certain herbs do exist, although they do not affect all people in the same way. This list is by no means exhaustive, but it is meant to be used as an example of potential interactions that can occur without research. For instance:

Black Cohosh and Green Tea Weight Loss Products

In some individuals, black cohosh may enhance liver toxicity.  Black cohosh is commonly used to treat issues such as menopause, therefore using this herb with another herb that can also cause liver toxicity would not be wise. While there have been no reports that green tea can also induce liver toxicity (and most studies show the opposite, with lower levels of AST and ALT), drinking green tea infusions such as weight loss products have been linked to liver issues in a very small number of people, reports National Institutes of Health.

Cranberry, Chamomile, Ginseng and Saw Palmetto

While cranberry and chamomile tea are both absolutely delicious, both herbs can have a negative effect on people taking blood thinners like warfarin. Combining both types of tea can potentially result in dangerous side effects.

Also, always check tea for additional ingredients like saw palmetto or the ever popular ginseng, as both herbs can also potentially contribute to issues with blood clotting as well. For some individuals, ginseng can affect insulin levels and blood pressure, along with pharmaceutical interactions.

Valerian and Kava

Individuals who use valerian root should be cautious when combining other herbs, as over 500 known reactions to the herb are currently known, reports While some of these reactions are related to medications rather than herbs, many herbal teas provide medicinal effects similar to those of pharmaceuticals, meaning there is a potential for a negative reaction to occur. Valerian is often used to decrease anxiety or induce sleep, meaning it isn’t wise to use this tea with other potent sleep inducing herbs such as kava. In fact, as a general rule, kava should not be used with other herbs, as liver toxicity can occur with improper use.

Herbal Teas


Anyone who isn’t sure about the safety of drinking more than one herbal tea per day should speak to a qualified professional. Individuals who take medications or a wide range of herbal supplements should speak with their physician and a licensed alternative therapist before combining multiple teas. While herbal remedies, including teas, have unlimited positive potential, the same herbs can lead to dangerous negative side effects when taken improperly. Always research and take the recommended dosage of any herb, including teas.
