Theina refers to a chemical compound known as theobromine, commonly found in different plant species, especially in cacao beans. It belongs to the group of methylxanthines and is closely related to caffeine. Theina exhibits stimulant properties similar to caffeine; however, it is generally less potent and milder in terms of its effects on the central nervous system.
Theina is a natural stimulant that acts as a vasodilator, promoting the expansion of blood vessels, and increasing blood flow. It also functions as a diuretic, promoting the excretion of fluid and increasing urine production. Additionally, theina acts as a bronchodilator, facilitating the relaxation and expansion of bronchial muscle, thus enhancing the efficiency of air exchange in the lungs.
Furthermore, theina has been reported to possess some physiological effects on the cardiovascular system, such as reducing blood pressure and lowering the risk of heart disease. Its stimulating properties can also lead to heightened alertness, improved mood, and enhanced cognitive performance.
While theina is primarily found in cacao beans, it is also present in smaller quantities in other plants, such as tea leaves, coffee beans, and guarana seeds. Due to its mild stimulating effects and association with functional foods, theina is often used as an ingredient in various dietary supplements and functional beverages to provide consumers with a natural energy boost without the side effects associated with higher caffeine consumption levels.
A bitter and volatile principle, obtained in the form of fine white prisms, of a silky lustre, from tea, coffee, &c.; same as caffeine.
