While scientific research in this field is lacking, and most positive information is based on experience from patients, there has been some study into the effects of IPT. In an article appearing in the European Journal of Cancer and Clinical Oncology, Vol. 17, 1981, Alabaster et al. of the Cancer Research Laboratory, George Washington University, Washington, D.C. have published experimental results showing that insulin increases the cytotoxic effect of methotrexate in MCF-7 human breast cancer cells in vitro by a factor of up to ten thousand.
My personal favorite so far for promoting relaxation has got to be Valerian root. Like a lot of the others in this list of herbs Valerian was probably first used by the Greeks and Romans centuries ago. They used Valerian to treat disorders associated with the liver, urinary tract and digestive tract. Valerian was once used to treat people suffering from the plague. Your cat will love Valerian too! People use to use Valerian in sort of the same way we use catnip today. Some people said that you could judge the potency of the Valerian by the reaction the cat had to the herb. In addition to being a cat attractant rats are also found of the foul smell and it was once used in rat traps. Today Valerian root is most commonly found as a sleep aid and anxiety relief supplement.
To treat colds or coughs you can make a nice ginger tea by cutting about one inch of ginger root into small pieces and adding to two cups of water and simmering for fifteen minutes. Ginger can also be found in capsules like a lot of other herbs and is a great way to get your dose of ginger for the day. Extracts are also available but are generally used only to treat osteoarthritis.
Bee Balm was often used by the Native Americans to treat intestinal problems, colic and flatulence. Tea made from this plant was used to induce sweating and break fevers. Bee balm is often used to treat the common cold and sore throat as well. The leaves of this plant are a good source of essential oil that contains thymol. Thymol is an antibiotic and often used as an ingredient in mouthwash.
