Caffeine, is a naturally produced medicine from the seeds and leaves of many plants. It is also produced unnaturally to add to certain foods. Caffeine is termed as a medicine because it arouses the central nervous system, causing enhanced alertness. Caffeine gives most people a short-term energy boost and bump up mood. Caffeine is present in tea, many soft drinks, coffee, chocolate, and pain relievers and other over-the-counter medicines. Caffeine tastes very bitter in its natural form. However, most caffeinated drinks undergo processing to cover-up the bitter taste. You may feel caffeine’s effects for up to 6 hours though it is not stored in the body.

Diiodotyrosine, also known as DIT, is a drug used to treat hyperthyroidism and is often included in dietary supplements designed to increase the metabolism and burn fat. It is considered a synthetic anti-thyroid agent that is used to decrease the amount of hormones the thyroid produces. In some cases it produces a response more quickly than radioactive iodine therapy while not causing the thyroid gland permanent damage. Possible serious side effects of this drug are the suppression of bone marrow which can lead the patient to having a decreased number of blood leucocytes, bronchitis, hepatitis, jaundice, skin rashes, and/or syndromes that are similar to systemic lupus erythematosus.

Evodiamine, an alkaloid extract from the Evodiae Fructus plant is known as Evodiamine. It has been referred to as a “hot nature” herb in Chinese literature and medicine. Based on animal studies, Evodiamine increases the natural fat burning rate and stimulates vanilloids for reduction of fat intake. It increases body temperature, influences the adrenal glands to secrete catecholamines and also affects the metabolism of certain drugs. Since it acts like a thermogenic and increases the overall temperature, more fat and calories are burnt due to its intake. This alkaloidal compound has anti obesity effects due to UCP1 (uncoupling protein 1) thermogenesis. In part, evodiamine can prevent diet induced obesity from developing further. It is available in the form of supplement or through Evodiae Fructus plant.

Green Tea Extract- Camellia sinensis, or more commonly the tea plant is a genus of flowering plants which is generally being used to produce tea, including green tea, oolong, black tea, white tea and pu-erh tea, also called Bolay tea. The different oxidation process makes the final difference. Tea plants can grow out into a tree, but are generally pruned to allow for easy hand picking. While camellia sinensis is being cultivated all around the globe in tropical and subtropical regions, this South and Southeast Asian native is most popular when imported from India and China. Medical uses of tea stem from the traditional Chinese medicine, where it was used as a bronchodilator and to treat angina pectoris, coronary artery disease and peripheral vascular diseases. Green tea extract is used as appetite suppressant and thermogenesis increasing agent.

Iodotyrosone, which is a form of tyrosine with iodine added.

L-Tyrosine, a non-essential amino acid that is used to build protein. It is a precursor dopamine, as well as a precursor to norepinephrine and epinephrine. The body makes L-Tyrosine from the amino acid phenylalanine. Since L-Tyrosine is a precursor of Dopamine, it may raise mental alertness, making it of great use in exercise programs.

Naringin is the major flavonoid glycoside in grapefruit and gives grapefruit juice its bitter taste. It occurs naturally in all citrus fruits so it is also called citrus Naringin. It is used in medicine for its pharmacological effects such as an antioxidant and for blood lipid lowering. Research also shows that Naringin can be used for inhibition of selected drug-metabolizing cytochrome P450 enzymes, including CYP3A4 and CYP1A2. Its anti-cancer effects are also being studied by researchers. Naringin is treated with potassium hydroxide or another strong base, and then catalytically hydrogenated to make naringin dihydrochalcone, which is used as a sugar-free sweetener 300 times sweater then sugar.

Octopamine, which is a trace amine, recently believed to be a lipotropic for fat loss. Octopamine has low oral bioavailability and is readily broken down by MAOI, as well as metabolized by the gut wall, which may mean it would not work well when taken orally, but more research is needed to prove its positive or negative effects.

Synephrine is a drug that is deemed to selectively bind to and also activate alpha adrenergic receptors. Mainly used as a vasoconstrictor in asthma, glaucoma, circulatory failure and nasal congestion, this compound is currently propagated as a weight loss agent. The alleged function synephrine is providing include fat burning, energy level and metabolism increase and promotion of weight loss. Synephrine, also known as oxedrine, is the widely accepted replacement for ephedrine. The natural source of synephrine is the citrus aurantium fruit, better known as bitter orange. Bitter orange extracts, which contain synephrine, are known to stimulate the alpha-1 adrenergic receptor, thereby constricting blood vessels and increasing the heart rate as well as blood pressure, effecting in an increased energy use.

Yerba Matte is potent and refers to a drink that is brewed with dried leaves. It belongs to the holly family that is an evergreen member. This grows in Peru, Argentina, Brazil and Chile. This is as well found in plenty in Paraguay. The Yerba Mate plant is considered as stimulant, aromatic, astringent, bitter, purgative, diuretic and good for inducing sweat and reducing fever. Yerba mate contains many minerals and vitamins. The Yerba Mate leaf has nutrition and antioxidants in plenty and hence North Americans prepare strong tea using this leaf. Yerba mate powder is used to boost immunity and to detoxify blood, restore hair color, combat fatigue, tone nervous system, stimulate mind, control appetite, retard aging, reduce stress and as well eliminate insomnia. The tea is preferred with sugar or some people add mint and few replace the water with milk. The extraction can be done repetitively so that the properties stay beneficial.
