Green tea ‘can impede nadolol blood pressure medicine’

ID-100153192In a study published in the journal of Clinical Pharmacology & Therapeutics, researchers discovered that patients taking the blood pressure lowering medication, nadolol, who also drank green tea, had lower blood levels of the drug. Follow-up tests were executed and exposed that green tea can block a transporter in the lining of the stomach that aids in pumping the drug into cells. Investigators theorize that a few cups of the tea would be enough to cause this inhibition of blood pressure lowering effect.

Hybrid Grapefruit May be Medically Safer

CEF_0137Grapefruit interacts with more than 85 drugs due to the organic chemical furanocoumarins, which inhibits drug metabolism, leading to drug  accumulation in the bloodstream. This can lead to serious adverse effects that may be fatal. Researchers have developed a hybrid grapefruit, with lower levels of this chemical, which has shown no serious adverse effects in human cell culture. Human clinical trials still have to be performed to determine its safety. What are your thoughts regarding this hybrid fruit?
