Caffeine is a bitter, white crystalline xanthine alkaloid that is a psychoactive stimulant drug. Caffeine is found in varying quantities in the beans, leaves, and fruit of some plants, where it acts as a natural pesticide that paralyzes and kills certain insects feeding on the plants. It is most commonly consumed by humans in infusions extracted from the cherries of the coffee plant and the leaves of the tea bush, as well as from various foods and drinks containing products derived from the kola nut. In humans, caffeine has a stimulant effect, causing increased amounts of stimulatory neurotransmitters to be released. If the consumption of caffeine is…
According to GCP#3 i.e. Less hazardous chemical synthesis: extraction of crude caffeine pose little toxicity to human health and the environment.(1)…
We successfully extracted 0.0117g of solid crude caffeine from a brewed beaker of tea, and found the melting point to be lower than the literature value given. The percentage yield for this experiment (based on the manufacturers’ claim of 55mg per bag of tea) was 21.27%. It was also determined that from 2.2894g of tea leaves, caffeine only contributed to 0.511% of that weight.…
Caffeine is found in coffee, tea leaves, cocoa beans, and kola nuts. It is used in prescription and over the counter drugs. It increases blood pressure, mental alertness, and gastrointestinal motility. Cardiovascular development with caffeine and other small molecules can be studied relatively easy using zebrafish. The cardiovascular system is complete in two days after fertilization.…

Caffeine is found in many plant species, where it acts as a natural pesticide. It is found most commonly in cocoa, tea and coffee, but is also artificially added to some soft drinks such as cola to act as a flavour enhancer. When consumed by humans, caffeine works as a stimulant causing amounts of released neurotransmitters to be increased. High use of caffeine has been related with raised blood pressure, restlessness, insomnia and anxiety which, in the long term, can lead to heart and circulation problems.…
The study used for this project is a nursing and health sciences study. One particular healthcare facility is trying to determine if it is a good idea to provide coffee in the waiting room for the patients. There are several other facilities that serve tea, coffee, and water, so this health care facility wants to determine if there is sufficient evidence to show that coffee increases the patient heart rates.…
Caffeine is a natural stimulant that nature, acts as a powerful insecticide used by plants to help them deter various insects from eating them. It is commonly found in coffee beans and tea leaves, as well as cocoa beans as well. Experts are now able to isolate this potent stimulant, and not only add it to various health supplements, but also offer it in its raw and natural state. It is especially popular amongst athletes and bodybuilders for the following…
Coffee, tea and chocolate all contain caffeine. It is also added to some soft drinks and energy drinks as well an ingredient in some painkillers and cold remedies. The average cup of coffee contains around 40mg of caffeine per cup, a can of cola around 23mg, and some energy drinks have four times that amount. Plain chocolate has 40mg caffeine per 100g – nearly three times as much as milk chocolate Drugs…
That boost we get from that morning cup of coffee is the result of the caffeine that naturally occurs in coffee. Caffeine is a common stimulant and is found not only in coffee and tea, but also in soft drinks and other foods. It can also be bought over-the-counter in tablet form. Too much caffeine can cause anxiousness, headaches, and the "jitters." Caffeine is also addictive and a person who abruptly stops drinking coffee may experience withdrawal symptoms.…
The benefits of caffeine seem to be really promising, but I fell they are just superficial. The benefits of caffeine are just a mask to the real problem. For instance people drink caffeinated beverages to stay awake for extended periods of time like for studying, long road trips and many other reasons. Caffeine just seems to be a crutch for not sleeping. Caffeine is also used to combat low energy levels which are usually caused by not enough sleep. Caffeine is just like any other drug, it works great the first couple of times, then the more it is used, the greater amount is needed to cause the same effects as the first use. Caffeine is a stimulant type drug; there should be no reason for using caffeine as a quick fix as frequently as Americans do. The beverage industry is thriving on the world’s population having a drug addiction. According to the International Olympic Committee, they are currently list caffeine as a restricted drug. Urinary levels up to a concentration of 12 mg/liter are acceptable, anything above these levels are viewed as deliberate doping, for performance enhancement. (Caffeine and athlete)If the Olympic Committee has reason to ban caffeine from all its athletes then caffeine should be banned from all…

Dated back to the 1400s and possible earlier people have been drinking caffeine to include coffee, tea, and chocolate. Today, caffeine is one of Americans’ favorite substance also including the soft drinks and the energy drinks. Per Hart and Ksir (2015) by 2009 Americans were consuming less caffeine; 45 gallons of soft drinks and 23 gallons of coffee when compared with 49 gallons of bottled water per person. Although declining, soft drinks and coffee are still a major part of American’s caffeine consumption, “it is estimated that 80 percent of Americans regularly use caffeine in some form,” (Hart & Ksir, 2015, p. 261). But the Food and Drug Administration (FDA) has not challenged its regulatory oversight on the caffeine use since the 1980s. Adults caffeine use is not of great concern by the FDA because there is no caffeine use disorder, the caffeine is responsible for long-term health benefits, and the caffeine is safe for most adults. Therefore, I consider the FDA current lack of restrictions on caffeine use sufficient and fair.…
