One of the medicinal components in tea that aligns with human organs is alkaloids.

The primary alkaloids in tea include theophylline, caffeine (theine), theobromine, and adenine, with caffeine being the most abundant.

Caffeine stimulates the central nervous system (brain, brainstem, spinal cord), acting as a reviving agent for depressed respiratory and vasomotor centers, and also serving as an antidepressant.

It enhances cerebral cortex activity, alleviating fatigue and drowsiness while boosting mental alertness.

Theophylline is used to treat heart failure; acts as an antiasthmatic by relieving bronchospasm; and has notable diuretic effects.

The benefits of tea alkaloids include:

1. Enhancing mental clarity and reducing fatigue

2. Aiding in sobering up and quitting smoking

3. Diuresis, managing hypertension, and strengthening the heart

4. Aiding digestion

5. Effectively preventing cardiovascular diseases
