Benefits of Herbal Tea

Consuming herbal teas aids digestion, detoxifies the body, promotes better sleep and relaxation, boosts circulation, and boosts immunity. For example, chamomile tea improves mood and reduces stress due to its calming effects and bacteria-fighting properties. Ginger root helps fight off colds and flu, and soothes digestive issues like upset stomach and nausea.

Herbal teas are a natural source of hydration and can be taken with other nutritious foods like fruits and vegetables to lose weight. Minerals in certain herbs, like calcium in raspberry leaf, keep bones healthy. Herbs like nettle leaf are high in iron, so drinking herbal tea may help those who don’t get enough iron from their diets.

Herbal teas are safe when made properly. Side effects may occur from occasional digestive discomfort or allergic reactions. It is important to consume herbs responsibly to enjoy the many benefits of herbal teas!

Types of Herbal Tea

Herbal teas are brewed from plants, herbs, and spices. Countless flavors and types exist. For centuries, these teas have been used to aid health. Alone or combined, they provide a range of taste, intensity, and effects.

Know the tea types and their side effects before drinking:


Chamomile is a famous herb, used for medicinal purposes for a long time. Its calming effects make it a popular beverage, chamomile tea. However, some side effects can come along with it. Ingredients like flavonoids in the tea are responsible for its sedative effects.

Generally, drinking up to 10 cups of chamomile tea per day is safe. Yet, some minor side effects, such as stomach issues, dizziness, headaches and nausea may come with it if taken in more than the recommended amount. Furthermore, people with allergies to ragweed, chrysanthemum, feverfew or marigold plants should be careful when drinking it.

Prior to having chamomile tea, it is wise to consult a doctor. This is because there may be interactions between the tea and medications taken.


Widely known, peppermint has lots of uses, including herbal teas. It can help with digestion, reduce gas, and offer relief from minor throat discomfort. Plus, it has calming properties that can help relax body and mind. Its caffeine-free too!

When using peppermint for tea, make sure it’s premium grade organic. Best to skip the sweeteners and other extra flavors, as they could override beneficial effects.


Ginger is an ancient herb with strong anti-inflammatory properties. Brewing it into tea offers therapeutic and delicious benefits! With 1-3 cups a day, ginger tea can help ease nausea, aid digestion and boost the immune system. Just be aware that consuming too much can cause gas, heartburn, throat irritation, and headaches.

Plus, complex carbs like bread or pastries should be avoided after drinking ginger tea. To be safe, it’s best to speak to your doctor before trying ginger tea if you’re taking medications or have health concerns. Enjoy ginger tea in moderation for the best results!


Hibiscus tea is quite popular. It has a tart flavor and a bright, ruby color! It’s made from the hibiscus plant, which usually grows in tropical and subtropical climates. The flowers are dried and used to make tea, while the leaves are extracted for medicinal properties.

Consuming hibiscus-based tea in moderation can help with digestion, weight loss, and lowering blood pressure and cholesterol. Plus, it can improve skin and promote healthy hair growth! It also boosts immunity and has anti-inflammatory properties, which can lessen arthritis symptoms.

Hibiscus tea is rich in vitamins and minerals, like vitamin C, flavonoids, and anthocyanins. People with allergies or who take certain medications should be cautious when drinking it. It may cause raised blood pressure or dizziness, and pregnant women should avoid it as it has diuretic effects.

It’s important to be aware that herbal teas and supplements can cause adverse reactions due to various factors, like drug interactions or intolerance of certain ingredients. If you experience any side effects, contact your doctor.


Echinacea is an herb with many medicinal benefits. It can be consumed both as a tea or in pill form, and researchers suggest it may help treat the common cold. However, before drinking echinacea tea, it is important to consult with a doctor. This is especially true if pregnant, taking medication, or have a medical condition.

Drinking too much of this herbal tea can cause nausea, dizziness, constipation, gas, and more serious health problems such as liver damage, rashes, and breathing difficulties. Therefore, it is recommended that individuals only drink moderate amounts of echinacea tea to avoid any potential side effects.

Side Effects of Herbal Tea

Herbal teas are usually viewed as safe. Yet, there can be some unintended effects. A few of these could be mild or serious. In this guide, we’ll examine the potential side effects of herbal tea and how to use them safely.

Allergic Reactions

When sipping herbal tea, be aware of potential allergic reactions to certain ingredients. People can experience various side effects, such as hives, rash or swelling. Anaphylactic reactions are possible with some herbs, so those with allergies should avoid these. Chamomile, nettle, fennel seed and rose hip are some of the ingredients that can cause allergies.

If serious allergic symptoms occur after drinking herbal tea, seek medical help immediately. Before consuming any tea, ask your doctor if there is a medication that interacts with it.

These symptoms may seem daunting, but they are rare. Many people enjoy herbal tea both hot and iced daily without any issues!

Interactions with Medications

It’s essential to keep an eye out for interactions between herbal tea and meds. Before consuming herbal teas, speak with your healthcare provider. This is especially important if you’re taking anticoagulants, sedatives, diuretics, contraceptives, or meds for anxiety or depression.

Herbal tea can also interact with dietary supplements. French maritime pine bark extract and evening primrose oil, when combined with nettle tea, can increase the risk of bleedings due to their antiplatelet properties. People on warfarin or heparin should be careful with nettle tea. Additionally, drinking cranberry juice or other cranberry-based products with nettle tea while taking aspirin or warfarin may raise the odds of bleedings. St John’s wort and valerian root may reduce the effectiveness of some antidepressants.

To stay safe, inform your healthcare provider about any herbs; beverages; dietary; and/or supplements being used, so they can adjust the dosage of prescription drugs if necessary.

Effects on Pregnancy and Breastfeeding

Herbal teas can be part of a healthy diet. But, pregnant and breastfeeding women should take extra caution. Caffeine can cross the placenta. Excessive caffeine has been linked to miscarriage and low birth weight. Traditional teas usually have little or no caffeine. Check labels for known stimulants.

Herbs may have medicinal effects, which can be beneficial in pregnancy or breastfeeding. But, herbs can also have adverse effects on a pregnant woman’s health and her baby’s health. Studies have shown some botanicals can be beneficial but can harm an unborn baby, when not taken with medical advice and supervision.

Herbs that reduce milk supply for a nursing mother include:

  • Sage
  • Parsley
  • Spearmint
  • Hibiscus tea (in large quantities)
  • Peppermint tea (in large quantities)
  • Chamomile (controversial, as it stimulates uterine contractions and could lead to miscarriage or preterm labor)

Seek permission from your health care provider before consuming any herbal tea while pregnant or breastfeeding. Certain herbs might cause potential problems worse than those they were meant to treat.

Tips for Safe Herbal Tea Use

Sipping herbal tea can be beneficial to your health. But, it’s crucial to know the side effects. Here are some tips for a safe herbal tea experience and potential risks you should be aware of. Stay informed!

Check the Ingredients

Consult with a Professional

Before drinking herbal tea, always check with a healthcare professional. They can tell you about any interactions with meds or supplements.
