Gyokuro
is a type of shaded green tea from Japan. It differs from the standard ''sencha'' (a classic unshaded green tea) in being grown under the shade rather than the full sun. The name "gyokuro" translates as "jewel dew" (or "jade dew"). While most sencha is from the cultivar of '' Camellia sinensis'', gyokuro is often made from a specialized variety such as Asahi, Okumidori, Yamakai, and Saemidori. Cultivation Though it is categorized as a type of sencha according to production methods, gyokuro cultivation differs from other sencha teas. Gyokuro tea leaves are shielded from the sun for at least 20 days before being harvested. This causes both the amino acid theanine and the alkaloid caffeine in the tea leaves to increase, which yields a sweet flavour. The tea also gains a distinct aroma from the covering process. Market Gyokuro is one of the most expensive types of sencha available in Japan. The name was originally the product name of the tea made by Yamamotoyama. The tea wa ...

Yamecha
Yamecha is a type of tea produced in Fukuoka Prefecture in Japan. It is cultivated in Yame-shi and its surrounding areas: Chikugo-shi, Hirokawa-cho, Ukiha-shi, and Asakura-shi. Yamecha makes up about 3% of Japan's green tea production and about 45% of Japan's gyokuro production on an annual basis. It is highly prized and one of the first regions in Japan to grow tea. The first tea plant in Yame was imported from China by a Zen priest named Eirin Suzui. Regional Characteristics The southern part of the Chikushi Plains is located in Yame-shi, where the Chikugo and Yabegawa rivers deposit rich sediment full of composted leaves. The Chikushi Plains is a region that has been famous for its tea cultivation since ancient times. It is the largest plain in Kyūshū and is located in the southern part of Fukuoka, extending to the Chikugo and Yabegawa river basins.

Theanine
Theanine , also known as L-γ-glutamylethylamide and ''N''5-ethyl-L-glutamine, is an amino acid analogue of the proteinogenic amino acids L-glutamate and L-glutamine and is found primarily in particular plant and fungal species. It was discovered as a constituent of green tea in 1949; in 1950, it was isolated from gyokuro leaves. Theanine provides a unique brothy or savory (umami) flavor to green tea infusions. The name "theanine" without a prefix generally implies the enantiomer L-theanine, which is the form found in tea leaves and as a dietary supplement ingredient. Most studies have used L-theanine. The opposite enantiomer, D-theanine, has been studied less. The regulatory status of theanine varies by country. In Japan, L-theanine has been approved for use in all foods, with some restrictions in the case of infant foods.Sakato,Y. J. Agri. Chem. Soc. 1949, 23, 262–267 In the United States, the Food and Drug Administration (FDA) considers it to be generally recognized ...

Japanese Tea
Green tea is a type of tea that is made from ''Camellia sinensis'' leaves and buds that have not undergone the same withering and oxidation process which is used to make oolong teas and black teas. Green tea originated in China, and since then its production and manufacture has spread to other countries in East Asia. Several varieties of green tea exist, which differ substantially based on the variety of ''C. sinensis'' used, growing conditions, horticultural methods, production processing, and time of harvest. The two main components unique to green tea are "catechins" and "theanine," and the health effects of these components are attracting a great deal of attention in Japan and abroad. History Tea consumption has its legendary origins in China during the reign of mythological Emperor Shennong. A book written by Lu Yu in 618–907 AD (Tang dynasty), ''The Classic of Tea'' (), is considered important in green tea history. The ''Kissa Yōjōki'' (喫茶養生記 ''Book of ...

Sencha
is a type of Japanese ''ryokucha'' (, green tea) which is prepared by infusing the processed whole tea leaves in hot water. This is as opposed to matcha (), powdered Japanese green tea, where the green tea powder is mixed with hot water and therefore the leaf itself is included in the beverage. Sencha is the most popular tea in Japan. Overview Among the types of Japanese green tea prepared by infusion, sencha is distinguished from such specific types as gyokuro in that it is shaded for a shorter time or not at all, or bancha which is the same tea but harvested later in the season. It is the most popular tea in Japan, representing about 80 percent of the tea produced in the country. The flavour depends upon the season and place where it is produced, but shincha, or 'new tea' from the first flush of the year, is considered the most delicious. Tea-picking in Japan begins in the south, gradually moving north with the spring warmth. During the winter, tea plants store nutrients, an ...

Caffeine
Caffeine is a central nervous system (CNS) stimulant of the methylxanthine class. It is mainly used recreationally as a cognitive enhancer, increasing alertness and attentional performance. Caffeine acts by blocking binding of adenosine to the adenosine A1 receptor, which enhances release of the neurotransmitter acetylcholine. Caffeine has a three-dimensional structure similar to that of adenosine, which allows it to bind and block its receptors. Caffeine also increases cyclic AMP levels through nonselective inhibition of phosphodiesterase. Caffeine is a bitter, white crystalline purine, a methylxanthine alkaloid, and is chemically related to the adenine and guanine bases of deoxyribonucleic acid (DNA) and ribonucleic acid (RNA). It is found in the seeds, fruits, nuts, or leaves of a number of plants native to Africa, East Asia and South America, and helps to protect them against herbivores and from competition by preventing the germination of nearby seeds, as well as ...

Nootropic
Nootropics ( , or ) (colloquial: smart drugs and cognitive enhancers, similar to adaptogens) are a wide range of natural or synthetic supplements or drugs and other substances that are claimed to improve cognitive function or to promote relaxation, particularly boosting mood, executive functions, attention, memory, creativity, or motivation in healthy individuals. The use of cognition-enhancing supplements by healthy individuals in the absence of a medical indication spans numerous controversial issues, including the ethics and fairness of their use, concerns over adverse effects, and the diversion of prescription drugs for non-medical uses. Nonetheless, the international sales of cognitive- or mood-enhancing supplements have continued to grow over time and in 2012 reached 0.69 billion. With sales supported by global health trends, the market is expected to reach US$33.85 billion by the year 2030, at a CAGR of 14.8%. While most nootropics are not regulated, there are ot ...
