Hydrastinine is a synthetic alkaloid prepared by various processes from either hydrastine, berberine, or narcotine. It exerts a strong stimulating action on the uterus of all species studied, including human. Hydrastinine and the closely related alkaloid cotarnine have been employed as hemostatics, particularly in abnormal uterine conditions. In the non-pregnant animal, hydrastinine in doses of 10 mg. depressed both tonus and activity, even after the section of the hypogastric. In the pregnant cat, it caused the uterus to contract. A stimulant action was also noted in the non-pregnant animal if nicotine were administered prior to hydrastinine. The rabbit uterus in situ was strongly contracted. Laidlaw believed that hydrastinine acted on the uterus both directly on the smooth muscle and also through its sympathetic innervation. Repeated administration of large doses for a period of time resulted in greatly increased amplitude of contractions which persisted after removal of the drug. The drug was patented by Bayer as a haemostatic drug during the 1910s.

QUININE HYPOPHOSPHITE, a salt of quinine, was formerly used, along with the hypophosphites of sodium, potassium, calcium, and iron, in the treatment of phthisis and neurasthenic conditions.

Melatonin (5-methoxy N-acetyltryptamine) is a hormone synthesized and released from the pineal gland at night, which acts on specific high affinity G-protein coupled receptors to regulate various aspects of physiology and behaviour, including circadian and seasonal responses, and some retinal, cardiovascular and immunological functions. Melatonin is also made synthetically and available without a prescription as an over-the-counter (OTC) dietary supplement in the U.S. Melatonin supplementation has many uses, however, it has been widely studied for treatment of jet lag and sleep disorders. Parents may consider using melatonin to help their child who has a trouble falling asleep. A medical professional should always evaluate insomnia or other sleeping disorders in children. Additionally, melatonin has been shown to protect against oxidative stress in various, highly divergent experimental systems. There are many reasons for its remarkable protective potential. In mammals, melatonin binds to a number of receptor subtypes including high-affinity (MT1 and MT2) and low-affinity (MT3, nuclear orphan receptors) binding sites, which are distributed throughout the central nervous system and periphery.

Cinchophen, phenylcinchoninic acid, seems to have been discovered in 1887 by Doebner and Gieseke and to have been introduced into medicine under the trade name of atophan in 1908 by Nicolaier and Dohrn. Since that time it has been used extensively for gout as well as for other forms of arthritis and for the relief of pain of all types. Use of Cinchophen in humans ceased in the 1930s due to the discovery that it can cause serious liver damage.

Antipyrine is an analgesic and antipyretic that has been given by mouth and as ear drops. It is often used in testing the effects of other drugs or diseases on drug-metabolizing enzymes in the liver. It inhibits cyclooxygenases and shows little anti-inflammatory activity. Like many old and approved substances after almost 100 years of use, antipyrine has been associated with some serious side effects, namely agranulocytosis and shock reactions.

Quinine ascorbate is a salt of antimalarial drug quinine and ascorbic acid (vitamin C). Ascorbate reduces the potency of quinolone-containing anti-malarial drugs. Quinine ascorbate was marketed as a component of over-the-counter smoking deterrent products but was not recognized as safe by the FDA regulation in 1993.

Ligustrazine (tetramethylpyrazine) is a bioactive ingredient extracted from the widely-used Chinese herb, Chuanxiong. It inhibits of platelet aggregation, enhances of vessel dilation, increases cerebral blood flow and possesses neuroprotective properties. The injection solution of ligustrazine has been used especially in China to treat ischemic stroke, coronary heart disease, diabetic nephropathy, and knee osteoarthritis. Ligustrazine was also evaluated in clinical as a remedy for pressure sores, as a salvage agent for patients with non-Hodgkin's lymphoma, as a treatment for bronchial asthma and vertebrobasilar insufficiency.

Perflunafene is a perfluorocarbon that can absorb, transport, and release oxygen and carbon dioxide. Perflunafene is a can be used as an alternative to red blood cell preparations to improve gaseous transport, in particular oxygen supply, to the tissues. Intra-ocular injection of perflunafene is used to provide temporary tamponade in ophthalmic procedures such as retinal re-attachment. Perflunafene and perfluamine have been used together for their oxygen-carrying properties in blood substitute preparations and to prevent myocardial ischaemia during percutaneous transluminal coronary angioplasty.

L-Theanine is a relaxing and nondietary amino acid found pretty much exclusively in teas from Camellia sinensis (alongside green tea catechins and caffeine) and is known to promote relaxation without sedation. It appears to be effective at this as well as reducing stress at standard dosages. L-theanine was discovered as a constituent of green tea in 1949 and was approved in Japan in 1964 for unlimited use in all foods, including chocolates, soft drinks, and herb teas, except infant foods. It also provides a unique umami (brothy or savory) taste and flavor to green tea infusion. L-theanine may help relieve stress by inducing a relaxing effect without drowsiness and may also possess immunologic attributes. Theanine may also have effects on the cardiovascular system and play a preventative role in cancer; however, limited clinical information is available to support these claims. L-Theanine and its positive effects on cognitive performance is one of its most important functions. Because of chemical structure of L-Theanine similar to glutamate it can act as a neurotransmitter related to memory. In a study made on rats, it was found out that L-Theanine modulated the serotonin and dopamine levels and increased learning skills with memory. In addition, it is stated that L-Theanine increases neuro - throphine mRNA level by activating its neuro - transmitter inhibiting system and supports the central nervous system that helps the development of brain functions. L-Theanine had a positive effect on memory and had positive effects on the treatment and prevention of Alzheimer. Theanine is an antagonist of the NMDA receptors (albeit with fairly weak efficacy) and can inhibit synaptic release of glutamate via blocking the transporter competitively. Theanine may also reduce glutamate levels, but this is also a fairly weak mechanism requiring a high concentration of theanine.

Resveratrol, a natural non-flavonoid polyphenol, exhibits a wide range of beneficial properties as an anticancer agent, a platelet anti-aggregation agent, and an antioxidant, as well as its anti-aging, anti-inflammatory, antiallergenic. This compound is in phase III clinical trials in combination with carboxymethyl-β-glucan for improving nasal symptoms in children with pollen-induced allergic rhinitis. Also in phase III clinical trial in the treatment of painful knee osteoarthritis and in type 2 diabetic patients. It has been demonstrated that resveratrol may prevent type 2 diabetic by targeting Sirtuin type 1 (SIRT1), indicating that SIRT1 may be a novel therapeutic target for diabetes prevention.
