The time it takes for herbal tea to start working can vary depending on several factors, including the individual's metabolism, the specific herbs used in the tea, and the desired effects. Generally, herbal teas are known to have a milder and more gradual onset compared to other beverages like coffee or energy drinks. In terms of immediate effects such as taste and aroma, you will notice those as soon as you start drinking the tea. However, if you're referring to the therapeutic effects of herbal tea, such as relaxation, digestion aid, or sleep promotion, it typically takes some time for the active compounds in the herbs to be absorbed and have an impact on the body. For many people, the effects of herbal tea start to become noticeable within 20 to 30 minutes after consumption. However, it's important to keep in mind that herbal teas often work through cumulative effects, meaning the benefits may increase gradually with regular and consistent use over a longer period. In some cases, it may take a few days or weeks of consistent consumption to experience the full effects of certain herbal teas. Remember that the specific herbs and their intended effects can vary greatly. Some herbs have immediate effects, while others may require more time to take effect. If you're using herbal tea for a specific purpose, it's advisable to consult the instructions or recommendations provided with the tea or seek guidance from a knowledgeable herbalist or healthcare professional.
