What Is Herbal Tea?
Herbal tea is a broad term that refers to beverages made by infusing herbs, spices, flowers, and fruits in hot water.

Popular herbal teas include:
- Chamomile tea: Known for its calming and sleep-inducing properties.
- Peppermint tea: Often used to ease digestive issues and soothe headaches.

Potential Health Risks of Herbal Tea
Despite the many benefits, not all herbal teas are risk-free. It's important to take herbal teas with caution, especially if you already have health problems, are pregnant or breastfeeding, or are taking medications. Here are some potential health risks you should be aware of:
1. Allergic Reactions
Herbal teas are made from a variety of plants and some people may be allergic to certain herbs. For example, chamomile tea is related to ragweed, which is a common allergen, and drinking chamomile tea may cause allergic reactions in people sensitive to ragweed. Symptoms of an allergic reaction can range from mild (itching or hives) to severe (anaphylaxis), so it's important to know your allergies and avoid herbal teas that may contain allergens.
2. Interactions with medications
Some of the herbs used in teas may interact with medications. For example, St. John's Wort tea is commonly used for its mood-enhancing properties, but it may also interact with medications such as antidepressants, birth control pills, and blood thinners.
Licorice tea may interfere with the immune system. Licorice tea may affect potassium levels in the body and may not be suitable for people with heart disease.
Before consuming herbal teas, it is important to check for potential interactions with any medications you are taking. Always seek advice from your healthcare provider, especially if you have concerns about a particular tea or ingredient.
3. Toxicity in certain herbs
While most herbs used in teas are considered safe, some can be toxic if consumed in large quantities or over long periods of time. For example, comfrey and pennyroyal, which were once used in herbal teas, are now known to be toxic to the liver and have been linked to serious health problems. Teas containing these herbs should be avoided, and it is important to buy your herbal teas from reputable suppliers who ensure safety and quality.
4. Pregnancy Concerns
Pregnant women should be especially careful with herbal teas. While some teas like ginger can help with pregnancy-related nausea, others can be harmful. For example, licorice tea can cause complications during pregnancy, and herbs like pennyroyal and mugwort should be strictly avoided as they have the potential to induce uterine contractions.
Herbs that are safe for one person may not be safe for another, especially during pregnancy, so it's important to consult a doctor before drinking herbal teas during this time.
5. Excessive consumption of certain herbs
While most herbal teas are safe when consumed in moderation, consuming certain teas in excess can cause health problems. For example, consuming licorice tea in excess can increase blood pressure and other cardiovascular problems due to a compound called glycyrrhizin. Likewise, drinking too much peppermint tea may cause digestive problems in some individuals.
As with any food or beverage, moderation is key. It's also a good idea to vary the types of herbal tea you drink to avoid overdosing on any one herb.
