Preparation and dosage:

Green tea can be used as hot water extract (tea) or powder.

History and dosage:

Tea can be divided into three common types: green tea, oolong tea and black tea, which are distinguished according to the different oxidation amount. Green tea inactivates oxidase and retains most catechins by flashing fresh tea leaves. Oolong tea is partially oxidized tea, and black tea is completely oxidized tea. The more oxidation occurs, the more catechins are removed. Black tea contains the most tannin and the least catechin. The key component that makes this plant an antioxidant, anticancer agent and antiviral agent is catechin EGCG (epigallocatechin gallate).

EGCG is an effective polyphenol, which is very effective in inhibiting cancer. EGCG has the functions of anti-inflammation, heart protection and anti-human papillomavirus, and can also protect the liver from many toxins such as chemotherapy drugs. EGCG also has antibacterial effect on Helicobacter pylori, which can reduce the production of dihydrotestosterone by inhibiting the activity of 5α reductase.

Other considerations:

It is very safe to use EGCG as a single component under normal therapeutic dose. Green tea and EGCG are effective inhibitors of iron absorption, so patients with hypochromic anemia should use them with caution.

It has been proved that EGCG can produce anti-anxiety activity by interacting with GABA receptor in brain. EGCG should be used with caution when treating patients with depression. If you try to get EGCG from green tea by soaking in hot water, please note that there will be more taboos due to the release of caffeine.

Caffeine-containing compounds are prohibited in pregnancy, breastfeeding, hypertension, anxiety, insomnia, moderate to severe nephropathy and young children.
