Since ancient times, infusions have been a popular way to obtain the benefits of medicinal plants. Civilisations such as the Chinese and Egyptian used herbs in hot water both to heal and to refresh. In European cultures, infusions were an integral part of traditional medicine, used by herbalists such as Nicholas Culpeper and Hildegard von Bingen. The tradition of using plants such as mint and hibiscus lies not only in their pleasant flavour, but also in their refreshing and beneficial properties for health.
In warm regions, cold infusions offer an effective way to stay hydrated without resorting to sugary or carbonated drinks. These preparations have been valued in various medical traditions, such as Ayurveda and Chinese medicine, for their ability to cool the body during the hot summer months. Today, scientific evidence supports many of these traditional uses, which promotes their global popularity and acceptance.
Cold infusions often contain natural ingredients such as mint, chamomile, hibiscus and ginger. Mint is rich in menthol, a substance that provides a sensation of freshness by activating in the mucous membranes. Hibiscus, on the other hand, is full of antioxidants such as polyphenols, which help combat oxidative stress in the body.
Chamomile contains apigenin, a compound that promotes relaxation and can help reduce anxiety. Ginger, known for its gingerol, is recognised for its anti-inflammatory and digestive properties. These plants, when infused in cold water, release their active components, offering a refreshing drink that not only hydrates, but also provides specific health benefits.
Numerous studies support the benefits of infusions. A study published in the “Journal of Nutrition” (2019) found that hibiscus can reduce blood pressure in adults by inhibiting an enzyme that affects blood vessel constriction. Additionally, a systematic review in the Cochrane Library (2018) highlighted the effectiveness of chamomile in relieving mild anxiety and stress.
Mint has also been the subject of scientific studies. An article in “Phytotherapy Research” (2020) showed that menthol has thermoregulatory properties, making mint infusions particularly refreshing during hot weather. These findings confirm that cold infusions are not only traditional but also scientifically backed for their health benefits.
Preparing cold infusions is simple and accessible. For a basic preparation, place two tablespoons of dried herbs or a tea bag in one litre of cold water. Leave it to rest in the fridge for at least 4 hours or overnight for a more intense flavour. You can sweeten it lightly with honey or add slices of citrus fruits to increase the antioxidant benefits.
It is recommended to consume these infusions two to three times a day to maintain hydration. Hibiscus and mint infusions are especially refreshing and can be consumed daily without concerns. However, it is always advisable to ensure that the herbs used are of quality and preferably organically grown.
Although infusions are generally safe, some people need to take certain precautions. For example, hibiscus can lower blood pressure, so those who already have hypotension should consume it with caution. Pregnant women should avoid liquorice, which is sometimes included in blends, due to its possible hormonal effects.
It is always better to consult a health professional before incorporating new herbs into your diet, especially if you are taking medications or have pre-existing health conditions. Let us remember that each organism is different and may react in a unique way to medicinal plants.
In Ayurveda, mint infusions are essential for balancing the pitta dosha, which is associated with heat. In Tibb al-Nabawi, chamomile and ginger are valued for their digestive and calming properties. Mexican cultures have also used hibiscus, known as “agua de jamaica”, for its ability to cool and refresh the body.
These traditional practices remain alive and are combined with modern discoveries to maintain their relevance. Throughout the world, infusions not only have a functional purpose, but also a cherished place in rituals and daily customs, symbolising the connection between nature and human wellbeing.
