Green Tea

Green Tea: A Distinctive Tea from Camellia Sinensis

Green tea, derived from the leaves and buds of the Camellia sinensis plant, stands apart due to its unique processing method. Unlike black and oolong teas, green tea avoids oxidation through steaming, pan-frying, or drying shortly after harvest. This preserves its natural antioxidants and imparts a distinct flavor and color.

Varieties of Green Tea

Factors like the variety of C. sinensis, growing conditions, and production methods result in diverse green teas. Japanese Sencha offers a delicate, light flavor, while Chinese Dragon Well provides a robust, slightly sweet profile.

Health Benefits of Green Tea

Green tea is celebrated for its high content of bioactive ingredients, especially polyphenols like epigallocatechin gallate (EGCG).

Antioxidant and Anti-Inflammatory Effects

Green tea polyphenols exhibit antioxidant, antiviral, and anti-inflammatory properties, protecting against heart disease and certain cancers.

Cardiovascular Health

Polyphenols in green tea modulate detoxification enzymes, stimulate immune function, and decrease platelet aggregation, promoting cardiovascular health.

Cancer Prevention

Studies suggest green tea polyphenols may delay the onset of cancer risk factors through effects on gene transcription and cell proliferation.

General Wellbeing

Green tea aids in weight loss, improves brain function, and supports overall wellbeing.

Preparing Green Tea

Brewing green tea requires attention to water temperature, steeping time, and tea quantity.

Water Temperature and Steeping Time

Ideal water temperature is 160°F to 170°F (71°C to 77°C). Steeping time ranges from 1 to 3 minutes, varying by tea type.

Sencha is rich in catechins, particularly EGCG, which provide antioxidant and anti-inflammatory benefits. Regular consumption may reduce the risk of chronic diseases and support cardiovascular health.

Matcha

Matcha contains higher concentrations of antioxidants compared to other green teas. Its L-theanine content promotes relaxation and improves focus, while its catechins support metabolism and detoxification.

Chinese Dragon Well (Longjing)

Dragon Well tea is known for its high vitamin C content and polyphenols, which enhance immune function and protect against oxidative stress. Its amino acids contribute to improved mental clarity and relaxation.
