Herb cold brew combines ancient traditions with modern trends. Historically, herbal infusions were an essential part of traditional medicine in cultures around the world. In China, more than 2,000 years ago, herbal teas were used to cool and calm the body according to the Shennong Bencao Jing (Compendium of Materia Medica) (Li Shizhen). In the Mediterranean, herbs such as mint and thyme were used in infusions to take advantage of their refreshing properties, based on texts by Dioscorides.
Today, cold brew, or cold extraction, transforms these traditions into a modern drink. The preparation requires no heat, preserving the volatile and delicate compounds of the herbs. This technique is popular in warm places, offering refreshing relief without losing the benefits of the herbs. It is a refreshing evolution that honours the past while adapting to the present.
The herbs used in cold brew have active components with known effects. Mint, for example, contains menthol, which has refreshing and digestive properties (ESCOP Monographs). Chamomile includes apigenin, a compound that could calm the nervous system (Blumenthal, 2000). Hibiscus provides antioxidants such as anthocyanin, which can help cardiovascular health (Duke, 2002).
When making cold brew, the cold immersion process extracts these compounds gently, avoiding destruction by heat. This results in a more aromatic and less astringent drink, maximally preserving the natural properties of the herbs. Thus, cold brew becomes an option that is not only refreshing, but also functional and beneficial for health.
Numerous studies support the benefits of herbal infusions. A study published by McKay and Blumberg (2006) in the Journal of Herbal Pharmacotherapy showed that chamomile infusion can reduce anxiety. Another study in the Journal of Nutrition showed that hibiscus can contribute to reducing blood pressure (McKay et al., 2010). These findings are consistent with uses in Ayurvedic and traditional Chinese medicine, where herbs have been valued for their relaxing and medicinal properties.
Official sources such as the European Medicines Agency (EMA) support the use of certain herbs in the treatment of digestive and nervous disorders. This shows that herbal infusions, even in cold brew format, are not only well-established traditions, but also practices supported by modern science.
Preparing an herb cold brew is simple. You will need your favourite herbs: mint, chamomile or hibiscus are good options. Place approximately 15 grams of herbs in one litre of cold water. Leave to steep in the fridge for 12–24 hours. Strain the herbs and enjoy your drink.
Adjust the amount of herbs to your taste. To sweeten, add a little honey or lime when serving. Enjoy this ideal drink on a warm summer day. If you follow any dietary restrictions, consult the recommended doses in monographs such as those from ESCOP to ensure you do not exceed them.
Although herbal infusions are generally safe, some precautions are necessary. People with allergies to these plants should avoid consuming them. In addition, certain herbs can interact with medications, so it is key to consult a professional if you are taking medication.
Pregnant or breastfeeding women should also be cautious. Overusing certain infusions can cause unwanted effects. It is always advisable to start with small amounts and observe how your body reacts.
Herbal infusions have a prominent place in various cultures. In Tibb al-Nabawi, the use of certain herbs to refresh the body and spirit is recommended. In Morocco, mint is widely used in cold teas due to its ability to ease body heat (Journal of Ethnopharmacology).
The Hawaiian tradition uses cold hibiscus infusions as a way to honour the land and natural resources, uniting community and nature. Each culture contributes its unique knowledge, enriching the contemporary practice of cold brew.
