Matcha is a type of green tea that has been part of Japanese culture for centuries. Its history begins in China, but it was in Japan that it reached its maximum expression, especially with the Zen monks who used it for meditation. In the 12th and 13th centuries, the Japanese monk Eisai introduced the tea cultivation method that we know today as matcha. This tea is ground into a fine powder, different from ordinary green tea which is only infused; so when you drink matcha, you ingest the entire tea leaf.
Traditionally, it has been consumed hot in tea ceremonies, but its worldwide popularity has grown, allowing adaptations such as cold matcha. According to classical texts and traditional medicine such as Tibb al-Nabawi, matcha is revered for its energising and antioxidant properties. This millennial combination of tradition and modern benefits makes matcha an attractive option for refreshing yourself in summer without losing its beneficial qualities.
Matcha is famous for its high levels of antioxidants, particularly catechins, which help combat cellular damage in the body. The most potent of these is EGCG (epigallocatechin gallate), known for its antioxidant and anti-inflammatory properties. Additionally, matcha contains L-theanine, an amino acid that can promote calm and improve concentration.
These compounds work together to provide a stable source of energy without the typical “crash” of caffeine alone. L-theanine modulates the effects of caffeine, allowing for a more uniform and prolonged state of alertness. This balance, combined with vitamins and minerals present in matcha, makes it a healthy option, suited both for moments of serenity and for more dynamic activities.
Numerous studies have explored the benefits of matcha. According to a study by Kuriyama and colleagues (2006) in the “Journal of American Medical Association”, regular consumption of green tea is associated with a reduced risk of cardiovascular disease (PMID: 16188995). Another study published by Nagao et al. (2005) shows that catechin consumption positively impacts the reduction of body fat (PMID: 15711042).
In the context of its cold use, an analysis by Zhou et al. (2020) in “Food Chemistry” confirmed that the antioxidant properties of matcha are maintained even when served cold. These findings support the use of matcha not only as a comprehensive wellbeing supplement but also as a refreshing drink in summer.
To enjoy cold matcha without losing its benefits, you can follow a simple recipe. Start by using 1-2 teaspoons of high-quality matcha powder. Sift the powder to avoid lumps and dissolve it in a little hot water. Then add ice and cold water, mixing well until you obtain a homogeneous drink. If you prefer a sweet touch, a little honey or agave syrup can be added.
By adapting it this way, matcha can form part of your daily routine, providing vitality and freshness without empty calories. According to WHO guidelines, it is safe to consume up to 3 cups a day, which makes a maximum of approximately 300 mg of catechins (WHO Monographs).
Despite its benefits, matcha should be consumed with caution by those sensitive to caffeine. Pregnant or breastfeeding women, as well as people with liver problems, should consult their doctors before incorporating matcha into their daily diet.
Excess matcha can lead to problems such as insomnia or gastritis due to caffeine. It is crucial to maintain recommended consumption levels and be alert to any unusual symptoms. According to the EMA, it is a safe practice with these precautions (EMA Guidance).
In traditional Chinese and Japanese medicine, matcha is considered for its ability to improve mental clarity and physical endurance. In Li Shizhen’s “Compendium of Materia Medica”, its revitalising effects and heart-protective properties are highlighted. In Japan, matcha is not only a cultural symbol but also an essential component in prolonged wellbeing practices.
Its ritualised use in tea ceremonies symbolises tranquility and mindfulness, central values in many Asian cultures. This cultural background adds even more value to the experience of consuming matcha in our daily lives.
