Wild oregano (Origanum vulgare), the strongest and most potent form of this herb, is seen as being the best form for the preparation of oregano oil. Its ability to slow down food spoilage has been known in the Mediterranean for centuries and is due to its anti-bacterial, anti-fungal, anti-parasitic and antioxidant activity which also accounts for the health benefits that some people have found when taking this amazing herb.
Scientists have demonstrated that the two principle actives, carvacrol and thymol, are mainly responsible for oregano's considerable anti-fungal and anti-bacterial action. Studies show that even tiny concentrations of these compounds can kill a wide variety of bacteria, fungi and parasites, many of which are associated with digestive problems such as ulcers, gastritis, bloating, flatulence and IBS. The volatile oils in oregano are smooth muscle relaxing, which further support its role in promoting relaxed digestion and a healthy gut.
Oregano has been shown to help with traveller's diarrhoea making it the ideal travelling companion. Evidence also suggests that oregano may be of value as part of an anti-candida programme.
Oregano has also been used in a variety of upper respiratory complaints such as sinus infections, sore throat, tonsillitis and bronchitis.
The antispasmodic attributes of oregano, combined with its expectorant properties account for the numerous historical references recommending oregano for alleviating coughs of various types.
