Green tea provides the benefit of preventing and treating radiation damage. Tea polyphenols and their oxidation products have the ability to absorb the toxins of radioactive substances strontium-90 and cobalt-60. Relevant medical clinical trials have confirmed that for cancer patients suffering from mild radiation sickness during radiotherapy, treatment with tea extracts achieved an effectiveness rate of over 90%; for leukopenia, the treatment effectiveness rate reached 81.7%; the treatment effect was even better for leukopenia caused by radiation.
Green tea has anti-aging benefits. The antioxidants found in green tea help resist aging of bodily functions. During the body's metabolic process, excessive oxidation produces large amounts of free radicals, which can easily damage and age cells. Superoxide dismutase (SOD) is a scavenger of free radicals, effectively clearing excess free radicals and preventing their damage to the human body. The catechins contained in green tea can significantly increase SOD activity and clear free radicals.
What are the benefits of black tea?
Drinking black tea offers many benefits for the body. Research indicates that black tea appears to improve vascular function in patients with coronary heart disease and can restore health to those with coronary artery sclerosis. Black tea is made through fermentation and baking; during fermentation, the tea leaves turn into red oxides under the action of oxidase, becoming black tea. Black tea has a mild nature and a mellow flavor. Besides containing various water-soluble vitamins, it is also rich in the trace element potassium, 70% of which can dissolve into the tea water after brewing. Potassium enhances heart blood circulation and reduces calcium consumption in the body. Because the manganese contained in black tea is one of the essential elements for bone structure, regularly drinking black tea is also beneficial for bone strength. Foreign reports suggest that regularly drinking black tea can also help prevent influenza, stroke, and skin cancer.

When considering the benefits of green tea and black tea for the body, the key is to identify which type of tea best suits one's own physical constitution.
