Antimicrobial activity : Effective in Inhibiting Pathogens That Causes Gastrointestinal Illness and Bloodstream Infections Agar well diffusion assay was carried out to determine antibacterial activities of bitter orange peels. One Gram Positive bacterium Bacillus cereus (foodborne pathogen that can produce toxins, causing two types of gastrointestinal illness: an emetic (vomiting) syndrome or diarrhoeal syndrome) and two Gram negative bacteria Shigella flexneri (causes shigellosis, which causes 1.1 million deaths and over 164 million cases each year) and Klebsiella pneumoniae (causes pneumonia, bloodstream infections, meningitis, and urinary tract infections). Among tested bacteria, marked inhibitory effect was observed against Klebsiella pneumoniae while Bacillus cereus was inhibited to least extent. Peel of Citrus aurantium caused marked inhibition of > 50 %. Source: Madhuri, S. ; Hegde, A. U. ; Srilakshmi, N. S. ; Prashith Kekuda, T. R. (2014). Antimicrobial activity of Citrus sinensis and Citrus aurantium peel extracts. Antifungal activities Poisoned food technique was performed to investigate antifungal efficacy of orange bitter peel against Colletotrichum capsici (causes Anthracnose in chilli, which usually associate with leaf tip die-back symptoms). Peel of Citrus aurantium caused marked inhibition of fungus to a high extent of 75 %. Source: Madhuri, S. ; Hegde, A. U. ; Srilakshmi, N. S. ; Prashith Kekuda, T. R. (2014). Antimicrobial activity of Citrus sinensis and Citrus aurantium peel extracts. Improve Cardiovascular Health In an interesting human clinical trial, orange juice was shown to elevate HDL cholesterol ("good" cholesterol) while lowering LDL (so-called bad) cholesterol. Oranges also help prevent cardiovascular disease by supplying folate, also called "folacin" or "folic acid" when used in supplementary form. Folate is one of the B vitamins and plays an important role in lowering blood concentrations of homocysteine. Homocysteine is an amino acid by-product of protein metabolism and its role in cardiovascular disease is significant. High levels of homocysteine have been implicated in cardiovascular disease and even vascular disease of the eye. The homocysteine that is allowed to build up in your body can damage your blood vessels and ultimately precipitate a "cardiovascular event" Interestingly, there is evidence that increased folate intake can actually improve heart health in people who have already developed heart disease.
