2 Caffeine
Caffeine is a compound found in many plants, such as coffee (Coffea arabica), cola nuts (Cola nitida), guarana (Paullinia cupana), mate (IIlex paraguarien-sis), tea (Camellia sinensts), and cacao (Theobroma cacao). Caffeine is a member of the methylxanthine alkaloid family along with two related compounds, theophylline and theobromine. These compounds are very similar chemically, differing only in the position of methyl groups, but they have different biochemical effects and are present in different ratios in caffeine-containing plants.
The effects of caffeine are well known. It increases the blood pressure, stimulates the central nervous system, promotes urine formation, and stimulates the action of the heart and lungs. Caffeine is used in treating migraine, increases the potency of analgesics such as aspirin, and can relieve asthma by widening the bronchial airways.
Purified caffeine is produced commercially chiefly as a byproduct in the making of decaffeinated coffee. Purified caffeine can be found in a variety of over-the-counter products, weight loss pills, including preparations to fight off sleep and increase mental alertness and in combination with acetaminophen or aspirin to treat headache or the fluid retention that can accompany menstruation.Caffeine-containing herbs can be used for these same purposes. In fact, due to their mild stimulatory action, many caffeine-containing herbs have historically been used to sustain people during long journeys or long hours of work in virtually every culture in the world. For example, cola nuts are used in West Africa; guarana is used by the natives of South America; coffee was originally used by East Africans and later by other cultures; tea is used by Asian cultures. Western societies seem to have adopted coffee as their herbal stimulant.
Caffeine and caffeine-containing herbs appear to be helpful in asthma, as regular caffeine consumption was found to be associated with a reduction in asthma symptoms. Numerous studies have shown that caffeine and theophylline (found in tea) are effective as mild bronchodilators. Also, a single cup of coffee was shown to offer a 29 percent reduced risk for adult-onset asthma. The public health implications of this may be important, as asthma is quite common in adults.Currently, perhaps the most popular use of caffeine-containing herbs is as ingredients in thermogenic formulas used in the promotion of weight loss (see ephedrine-caffeine combinations). Although caffeine, as well as caffeine-containing herbs such as guarana, tea, and mate, has been shown to in-crease the metabolic rate, combining it with ephedrine greatly increases this effect.
Caffeine is considered to be the most popular substance, stimulating agent that is usually extracted from cola nut, tea, guarana or coffee beans. It’s used in many different energy drinks because of it’s refreshing effects. People drink coffee with large amounts of caffeine in the morning to “wake up”. It is estimated that over 200 million people in USA consume caffeine daily. Caffeine can be addictive and long term use may be related to certain health issues. In weight loss industry caffeine is used as stimulant. It’s extract called trimethylxanthine – which acts as extremely strong stimulant on the human brain. It stimulates central nervous system and cardiac functions. It offers great energy boost and increases feeling of alertness. It stimulates sympathetic branch (CNS) and increases heart rate. It acts as booster of blood flow in to the muscles and helps liver to release glucose. CNS reacts with hormone called epinephrine that’s released from pituitary gland which influences growth and promotes metabolism.
Caffeine releases 3 major metabolites: Theobromine, Theophylline and Paraxanthine. Theobromine promotes oxygen and allowing nutrients flow faster to the brain. Paraxanthine helps with breaking down fat cells in to energy. Theophylline helps to relax muscles and increase heart rate.

Caffeine may have the potential to cause cardiac arrhythmia {irregular heartbeat). As a precaution, it is recommended that caffeine be avoided by individuals with a history of arrhythmia and/or palpitations and during the first month after suffering a heart attack.Chronic caffeine consumption can lead to physical and psychological dependence. If caffeine intake is stopped abruptly, physical signs of withdrawal may occur. The most common symptoms of caffeine withdrawal are fatigue and headache. These symptoms usually begin twelve to twenty-four hours after caffeine intake is stopped and may last as long as a week.
Caffeine side effects
Caffeine can produce anxiety, irritability, and insomnia, especially in people sensitive to these effects or already experiencing some degree of these difficulties. Other possible side effects include light-headedness, headache, nausea, gastric irritation, and vomiting.
Caffeine drug interactions
The breakdown of caffeine is inhibited by the following drugs: birth control pills, estrogen (e.g., Premarin), mexiletine, cimetidine (Tagamet), and various antibiotics (e.g., norfloxacin, enoxacin, and ciprofloxacin). Tricyclic antidepressant drugs, ephedrtne, and theo-phylline (used in asthma) all potentiate the effects of caffeine. Alcohol inhibits the breakdown of caffeine.To avoid the potential danger of caffeine overdose, be aware of your consumption of caffeine-containing foods and beverages.
Caffeine dosage
The typical dosage of caffeine as a stimulant is 100 to 200 mg no more than once every four hours and no less than six hours before bedtime. The dosage for the various herbal sources of caffeine is based upon supplying an equivalent amount of caffeine.
Caffeine over dosage
Doses of caffeine over 250 mg can produce definite signs of toxicity, such as stomach pain, nervousness, increased heart rate, elevation in blood pressure, frequent urination, and disordered thought and speech. More serious symptoms include arrhythmia (irregular heartbeat) and seizures. In the case of severe symptoms seek emergency treatment.
Caffeine and pregnant women
Caffeine is to be avoided during pregnancy and lactation. Caffeine has long been suspected of causing malformations in the fetus, although this is controversial. The dosage required for this effect is probably quite large, and the data are scant, as experimentation on humans is not feasible. Caffeine has been shown to cause malformations in rats when ingested at rates comparable to seventy cups a day for humans. In humans, daily doses of 300 mg per day or more in pregnant women have been linked to slowed growth and low birth weight of the infant.Caffeine passes into breast milk and may cause wakefulness and irritability in nursing infants.
Caffeine and children
There does not appear to be any appropriate use of caffeine or caffeine-containing beverages in children. The adverse effects of caffeine are usually more severe in children because their breakdown of caffeine is slower than that of adults.
Caffeine and seniors
Seniors are often more sensitive to caffeine's stimulant effects and may be more likely to experience nervousness, anxiety, and insomnia. Seniors are also more likely to be taking drugs that interact with caffeine.
