Matcha is a finely ground powder made from specially shade-grown green tea leaves. Unlike regular steeped green tea, the entire leaf is consumed, resulting in a much higher concentration of beneficial compounds. This concentrated nature leads many to seek out matcha as a potential remedy for common sicknesses like the cold. Scientific evidence suggests that matcha’s unique chemical profile offers both direct and indirect benefits that may help the body manage a viral illness.
Key Components in Matcha Relevant to Health
Matcha’s health properties stem from its abundance of two primary bioactive compounds: catechins and the amino acid L-Theanine. Catechins are a type of antioxidant, and the most prominent and well-studied in matcha is Epigallocatechin gallate (EGCG). Since the whole leaf is consumed, the concentration of EGCG in matcha can be significantly higher than in traditionally brewed green tea.
L-Theanine is a unique amino acid that is also concentrated in matcha due to the shading process. This compound is known for its ability to promote a state of relaxed focus by stimulating alpha brain waves. In addition to these two major components, matcha contains a range of vitamins, including Vitamin C, and minerals, which contribute to general health support.
Impact on Immune Function
The primary way matcha may support the body against a cold is through the biological actions of its catechins. EGCG exhibits potent antioxidant and anti-inflammatory properties, which are helpful when the body is under attack from a virus. The anti-inflammatory effect of EGCG can help to mitigate the excessive immune response that often causes cold symptoms like swelling and irritation in the respiratory tract.
Studies have indicated that green tea catechins may possess antiviral activity against certain viruses, including some strains of the influenza virus. These compounds may inhibit the replication of viruses or interfere with their ability to infect cells. Furthermore, the combination of L-Theanine and catechins has been shown to enhance specific markers of immune function, potentially leading to a reduced duration of cold and flu symptoms.
Hydration and Symptom Relief
Beyond the direct immune support, drinking warm matcha contributes significantly to managing the physical discomfort of a cold. Staying hydrated is a fundamental recommendation during illness, as it helps to thin mucus, replace lost fluids from fever, and soothe a sore throat. A warm cup of matcha provides a comforting and effective vehicle for increasing necessary fluid intake.
Matcha’s unique combination of L-Theanine and moderate caffeine content also addresses the common cold symptom of fatigue. L-Theanine works to modulate the stimulating effects of caffeine, resulting in a sustained energy boost without the excessive jitters or anxiety often associated with coffee. This can help an ill person feel more alert and functional.
