Perhaps the most well-known and popular beverage in Asia, from the past and still today, TEA.「Plant of emerging shafts, evening activity orifice, famous」refers to the high caffeine level in tea: tea contains caffeine, a drug to「get it started」affecting the meat of both orifices and shafts. Caffeine acts on the brain significantly as a psychoactive drug affecting increased levels of dopamine and other erection-causing hormones (recalling that females also experience erections of some bodily tissue, namely both mammalian teats, vulvar labia, vaginal vestibule, and the clitoral stem):
　「Inside the body caffeine acts through several mechanisms, but its most important effect is to counteract a substance called adenosine that naturally circulates at high levels throughout the body, and especially in the nervous system. In the brain, adenosine plays a generally protective role, part of which is to reduce neural activity levels – for example, there is some evidence that adenosine helps to induce torpor in animals that seasonally hibernate. …A reduction of adenosine also has profound effects on most of the other major neurotransmitters, including dopamine, acetylcholine, serotonin, and, in high doses, on norepinephrine as well as epinephrine, glutamate, cortisol, and to a small extent endorphins. …Because caffeine is both water-soluble and lipid-soluble, it readily crosses the blood–brain barrier that separates the bloodstream from the interior of the brain. Once in the brain, the principal mode of action is as a nonselective antagonist of adenosine receptors (in other words, an agent that reduces the effects of adenosine). The caffeine molecule is structurally similar to adenosine, and is capable of binding to adenosine receptors on the surface of cells without activating them, thereby acting as a competitive inhibitor. Adenosine is found in every part of the body…」
