Matcha tea rich in EGCG  helps fight various bacterial, viral, and fungal infections. According to a research study,  EGCG binds to the lipid membrane and exerts inhibitory action against the growth of various human pathogens. These include influenza A virus, hepatitis B, and C virus, herpes virus, adenovirus Staphylococcus aureus bacteria, and Candida albicans yeast.

Matcha used to be sold in packages of 10 monme (ancient measure of about 3.75 g, or 37.5 g for the package) and most tea masters considered that one package provided for 20 usucha (about 1.8 g each) or 10 koicha (about 3.75 g each). This is why today's traditional packaging is 40 g (the closest to 10 monme)
A juniper berry is not a true berry, but is a seed cone with unusually fleshy and merged scales that give it a berry-like appearance. Used as a spice in European cuisine, juniper berry has been used in traditional herbal medicine to support kidney and urinary tract function, as well as to help maintain healthy blood pressure levels that are already within the normal range. The essential oil can be stimulating to the kidneys. The warming and bitter properties support digestion and can soothe intestinal gas. Juniper berry can also be warming for the joints.

Matcha: This is the leftover powder of green tea, also called “Dust”. It makes a beautifully green-colored tea and forms a lot of foam (froth), but has a weaker aroma than the leafy varieties. This variety of green tea is very popular in traditional ceremonies and is sometimes also called Ceremonial Green Tea. It is far less bitter than the other three varieties, so when you sip it, it seems to hold a natural sweetness, particularly if you are familiar with the other varieties.

To make green tea, the leaves are quickly steamed or heated to stop oxidation, the chemical process that causes browning. To make black tea, the leaves are crushed, torn, curled, or rolled and allowed to oxidize before being dried. This additional processing step degrades some of the flavonoids. As a result, black tea has slightly lower amounts of flavonoids than green tea.

Shade grown: All matcha is made from shade-grown tea leaves—a labor-intensive process where tea bushes are protected from the sun and light is filtered to the bushes in a very controlled manor. Shading boosts the chlorophyll production in the plant, giving the leaves a rich green color. The lack of sun reduces the plant’s photosynthesis of the leaves, which in turn alters the naturally occurring levels of caffeine, flavanols, sugars, antioxidants, and theanine. By controlling the sun exposure, tea producers can significantly alter the chemical make-up and flavor of the final tea leaves.
