Quote from the lab manual:
Caffeine is present in tea leaves and in coffee to the extent of about 4%. Tea also contains two other alkaloids, theobromine and theophylline. These last two relax the smooth muscles where caffeine stimulates the heart and respiratory systems.
The effects of theobromine are, compared to caffeine and theophylline, relatively moderate. However, cocoa contains eight times more theophylline than caffeine. As well, caffeine has been shown to combine with other substances for added potency. Thus the effects of theobromine might be enhanced by the caffeine in chocolate.
Theobromine is highly toxic to dogs and kills many
Clinical signs of theobromine toxicity in canids usually manifest 8 hours after ingestion and can include: thirst, vomiting, diarrhea, urinary incontinence, nervousness, clonic muscle spasms, seizures and coma. Any dog thought to have ingested a large quantity of chocolate should be brought to an emergency clinic asap, where treatment usually includes the use of emetics and activated charcoal. The dog will thus need to be monitored to maintain proper fluid and electrolyte balance.
Pathogenesis of theobromine toxicity: evidently large quantities of theobromine have a diuretic effect, relax smooth muscles, and stimulate the heart and cns.

It is possible that in addition to caffeine, there is some other substance in guarana that also produces an effect, since it 'feels' different than coffee. Same goes for mate.Return to Index

Caffeine is an alkaloid. There are numerous compounds called alkaloids, among them we have the methylxanthines, with three distinguished compounds: caffeine, theophylline, and theobromine, found in cola nuts, coffee, tea, cacao beans, mate and other plants. These compounds have different biochemical effects, and are present in different ratios in the different plant sources. These compounds are very similar and differ only by the presence of methyl groups in two positions of the chemical structure. They are easily oxidized to uric acid and other methyluric acids which are also similar in chemical structure.
Sources: Coffee, tea, cola nuts, mate, guarana.
Effects: Stimulant of central nervous system, cardiac muscle, and
respiratory system, diuretic Delays fatigue.
Effects: Cariac stimulant, smooth muscle relaxant, diuretic, vasodilator
Sources: Principle alkaloid of the cocoa bean (1.5-3%) Cola nuts and tea
Effects: Diuretic, smooth muscle relaxant, cardiac stimulant, vasodilator.
(Info from Merck Index)
The presence of the other alkaloids in colas and tea may explain why these sometimes have a stronger kick than coffee. Colas, which have lower caffeine contents than coffee are, reportedly, sometimes more active. Tea seems the strongest for some. Coffee seems more lasting for mental alertness and offers fewer jitters than the others.

Caffeine is sometimes called "theine" when it's in tea. This is probably due to an ancient misconception that the active constituent is different. Theophylline is present only in trace amounts. It is more diuretic, more toxic and less speedy.
Coffee and tea contain caffeine and theophylline, respectively, which are methylated purine derivatives that inhibit cAMP phosphodiesterase. In the presence of these inhibitors, the effects of cAMP, and thus the stimulatory effects of the hormones that lead to its production, are prolonged and intensified.
Theobromine and theophylline are two dimethylxanthines that have two rather than three methyl groups. Theobromine is considerably weaker than caffeine and theophylline, having about one tenth the stimulating effect of either.
Theobromine is found in cocoa products, tea (only in very small amounts) and kola nuts, but is not found in coffee. In cocoa, its concentration is generally about 7 times as great as caffeine. Although, caffeine is relatively scarce in cocoa, its mainly because of theobromine that cocoa is "stimulating".
Theophylline is found in very small amounts in tea, but has a stronger effect on the heart and breathing than caffeine. For this reason it is often the drug of choice in home remedies for treating asthma bronchitis and emphysema. The theophylline found in medicine is made from extracts from coffee or tea.Return to Index

multimedia/images/gif/cTheobromine is also a common component of coffee, tea, chocolate, and mate (particularly in these last two).
Theophylline was once thought to be a major component of tea. This is not correct. Tea contains significantly more amounts of caffeine than of theophylline.

Yes and no. An espresso cup has about as much caffeine as a cup of dark brew. But servings for espresso are much smaller. Which means that the content of caffeine per millilitre are much higher than with a regular brew. Moreover, caffeine is more quickly assimilated when taken in concentrated dosages, such as an espresso cup.
The myth of lower caffeine espresso comes comes from the fact that the darker roast beans used for espresso do have less caffeine than regularly roasted beans as roasting is supposed to break up or sublimate the caffeine in the beans (I have read this quote on research articles, but found no scientific studies supporting it. Anybody out there?). But espresso is prepared using pressurized water through significantly more ground (twice as much?) than regular drip coffee, resulting in a higher percentage of caffeine per millilitre.

Important: This information was excerpted from several sources, no claims are made to its accuracy. The FAQ mantainer is not a medical doctor and cannot vouch for the accuracy of this information.
The best way to proceed is to consume caffeine regularly for a week, while keeping a precise log of the times and amounts of caffeine intake (remember that chocolate, tea, soda beverages and many headache pills contain caffeine as well as coffee). At the end of the week proceed to reduce your coffee intake at the rate recommended above. Remember to have substitutes available for drinking: if you are not going to have a hot cup of coffee at your 10 minute break, you might consider having hot chocolate or herbal tea, but NOT decaff, since decaff has also been shown to be addictive. This should take you through the works without much problem.
Some other people quit cold turkey. Withdrawal symptoms are quite nasty this way (see section below) but they can usually be countered with lots of sleep and exercise. Many people report being able to stop drinking caffeine almost cold-turkey while on holidays on the beach. If quitting cold turkey is proving too hard even in the beach, drinking a coke might help.
Regular caffeine consumption reduces sensitivity to caffeine. When caffeine intake is reduced, the body becomes oversensitive to adenosine. In response to this oversensitiveness, blood pressure drops dramatically, causing an excess of blood in the head (though not necessarily on the brain), leading to a headache.
This headache, well known among coffee drinkers, usually lasts from one to five days, and can be alleviated with analgesics such as aspirin. It is also alleviated with caffeine intake (in fact several analgesics contain caffeine dosages).
Often, people who are reducing caffeine intake report being irritable, unable to work, nervous, restless, and feeling sleepy, as well as having a headache. In extreme cases, nausea and vomiting has also been reported.

From Desk Reference to the Diagnostic Criteria from DSM-3-R (American Psychiatric Association, 1987):
Caffeine-Induced Organic Mental Disorder 305.90 Caffeine Intoxication
- Recent consumption of caffeine, usually in excess of 250 mg.
- At least five of the following signs:
- flushed face
- gastrointestinal disturbance
- muscle twitching
- rambling flow of thought and speech
- tachycardia or cardiac arrhythmia
- periods of inexhaustibility
- psychomotor agitation
- Not due to any physical or other mental disorder, such as an Anxiety Disorder.
Basically, overdosing on caffeine will probably be very very unpleasant but not kill or deliver permanent damage. However, People do die from it.
The LD_50 of caffeine (that is the lethal dosage reported to kill 50% of the population) is estimated at 10 grams for oral administration. As it is usually the case, lethal dosage varies from individual to individual according to weight. Ingestion of 150mg/kg of caffeine seems to be the LD_50 for all people. That is, people weighting 50 kilos have an LD_50 of approx. 7.5 grams, people weighting 80 kilos have an LD_50 of about 12 grams.
In cups of coffee the LD_50 varies from 50 to 200 cups of coffee or about 50 vivarins (200mg each).
One exceptional case documents survival after ingesting 24 grams. The minimum lethal dose ever reported was 3.2 grams intravenously, this does not represent the oral MLD (minimum lethal dose).
In small children ingestion of 35 mg/kg can lead to moderate toxicity. The amount of caffeine in an average cup of coffee is 50 - 200 mg. Infants metabolize caffeine very slowly.
The toxic dose is going to vary from person to person, depending primarily on built-up tolerance. A couple people report swallowing 10 to 13 vivarin and ending up in the hospital with their stomaches pumped, while a few say they've taken that many and barely stayed awake.
A symptom lacking in the clinical manual but reported by at least two people on the net is a loss of motor ability: inability to move, speak, or even blink. The experience is consistently described as very unpleasant and not fun at all, even by those very familiar with caffeine nausea and headaches.Return to Index
Caffeine has long been suspect of causing mal-formations in fetus, and that it may reduce fertility rates.
These reports have proved controversial. What is known is that caffeine does causes malformations in rats, when ingested at rates comparable to 70 cups a day for humans. Many other species respond equally to such large amounts of caffeine.
Data is scant, as experimentation on humans is not feasible. In any case moderation in caffeine ingestion seems to be a prudent course for pregnant women. Recent references are Pastore and Savitz, Case-control study of caffeinated beverages and preterm delivery. American Journal of Epidemiology, Jan 1995.
A recent study found a weak link between Sudden-Infant-Death-Syndrome (SIDS) and caffeine consumption by the mother, which reinforces the recommendation for moderation -possibly even abstinence- above.
On men, it has been shown that caffeine reduces rates of sperm motility which may account for some findings of reduced fertility.Return to Index
From the Journal of AMA: (JAMA, 26 Jan. 1994, p. 280-3.)
"There was a significant association between (drinking more) caffeinated coffee and decreasing bone mineral density at both the hip and the spine, independent of age, obesity, years since menopause, and the use of tobacco, estrogen, alcohol, thiazides, and calcium supplements [in women]."
"Bone density did not vary [...] in women who reported drinking at least one glass of milk per day during most of their adult lives."
That is, if you drink a glass of milk a day, there is no need to worry about the caffeine related loss of calcium.

OAKLAND, California (UPI) -- Coffee may be good for life. A major study has found fewer suicides among coffee drinkers than those who abstained from the hot black brew.
The study of nearly 130,000 Northern California residents and the records of 4,500 who have died looked at the effects of coffee and tea on mortality.
Cardiologist Arthur Klatsky said of the surprising results, ``This is not a fluke finding because our study was very large, involved a multiracial population, men, women, and examined closely numerous factors related to mortality such as alcohol consumption and smoking.''
The unique survey also found no link between coffee consumption and death risk. And it confirmed a ``weak'' connection of coffee or tea to heart attack risk -- but not to other cardiovascular conditions such as stroke.
The study was conducted by the health maintenance organization Kaiser Permanente and was reported Wednesday in the Annals of Epidemiology.Return to Index
Caffeine increases the level of circulating fatty acids. This has been shown to increase the oxidation of these fuels, hence enhancing fat oxidation. Caffeine has been used for years by runners and endurance people to enhance fatty acid metabolism. It's particularly effective in those who are not habitual users.
Caffeine is not an appetite suppressant. It does affect metabolism, though it is a good question whether its use truly makes any difference during a diet. The questionable rationale for its original inclusion in diet pills was to make a poor man's amphetamine-like preparation from the non-stimulant sympathomimetic phenylpropanolamine and the stimulant caffeine. (That you end up with something very non-amphetamine like is neither here nor there.) The combination drugs were called "Dexatrim" or Dexa-whosis (as in Dexedrine) for a reason, namely, to assert its similarity in the minds of prospective buyers. However, caffeine has not been in OTC diet pills for many years per order of the FDA, which stated that there was no evidence of efficacy for such a combination.
From Goodman and Gilman's The Pharmacological Basis of Therapeutics:
Caffeine in combination with an analgesic, such as aspirin, is widely used in the treatment of ordinary types of headache. There are few data to substantiate its efficacy for this purpose. Caffeine is also used in combination with an ergot alkaloid in the treatment of migrane (Chapter 39).
Ergotamine is usually administered orally (in combination with caffeine) or sublingually [...] If a patient cannot tolerate ergotamine orally, rectal administration of a mixture of caffeine and ergotamine tartarate may be attempted.
The bioavailability [of ergotamine] after sublingual administration is also poor and is often inadequate for therapeutic purposes [...] the concurrent administration of caffeine (50-100 mg per mg of ergotamine) improves both the rate and extent of absorption [...] However, there is little correspondence between the concentration of ergotamine in plasma and the intensity or duration of therapeutic or toxic effects.
Caffeine enhances the action of the ergot alkaloids in the treatment of migrane, a discovery that must be credited to the sufferers from the disease who observed that strong coffee gave symptomatic relief, especially when combined with the ergot alkaloids. As mentioned, caffeine increases the oral and rectal absorption of ergotamine, and it is widely believed that this accounts for its enhancement of therapeutic effects.
Nowadays most of researchers believe that the stimulatory actions are attributable to the antagonism of the adenosine. Agonists at the adenosine receptors produce sedation while antagonists at these sites, like caffeine and theophylline induce stimulation, and what is even more important, the latter substance also reverse agonists-induced symptoms of sedation, thus indicating that this effects go through these receptors.
Another possibility, however, is that methylxanthines enhance release of excitatory aminoacids, like glutamate and aspartate, which are the main stimulatory neurotransmitters in the brain.
As to the side effects: methylxanthines inhibit protective activity of common antiepileptic drugs in exptl. animals in doses comparable to those used in humans when correction to the surface area is made. It should be underlined, that although tolerance develop to the stimulatory effects of theo or caffeine when administered on a chronic base, we found no tolerance to the above effects . This hazardous influence was even enhanced over time. Therefore, it should be emphasized that individuals suffering from epilepsy should avoid, or at least reduce consumption of coffee and other caffeine-containing beverages.Return to Index

You won't get single, glossy beans, but the taste is there!
Here's the recipe for making a real chocolate beverage. Important steps are in boldface.
With oil, which gives you a richer flavour:
Spread aluminum foil on a table and make small pies of chocolate, about 1/4 of an inch high, and 6 inches in diameter. Let them rest overnight. The morning after they are hard tablets. Remove them from the aluminum foil and rap them in it. Store in the freezer.
Without oil, some flavour is gone, less bitter, weaker (whimper) chocolate:
Put the paste inside a thin cloth (like linen), close the cloth and squeeze until the oil comes out. If you manage to get most of the oil out, what is left is high quality cocoa powder, like Droste's.
What is left now is either bitter tablets or bitter cocoa powder.
You can now make a nice beverage as follows:
