- бергамот здоровью не противоречит Из английской: "Toxicology
In several studies, application of some sources of bergamot oil directly to the skin was shown to have a concentration-dependent phototoxic effect of increasing redness after exposure to ultraviolet light (due to the chemical bergapten, and possibly also citropten, bergamottin, geranial, and neral).[15][16] This is a property shared by many other citrus fruits. Bergapten has also been implicated as a potassium channel blocker; in one case study, a patient who consumed four liters of Earl Grey tea per day suffered muscle cramps.[17]
Bergamot contains extremely large amounts of polyphenols, as compared to other citrus species. Two of these, Brutelidin and Metilidin, directly inhibit cholesterol biosynthesis in a similar way to statins and they are not found in any other citrus derivatives.[18]
Bergamot is also a source of bergamottin which, along with the chemically related compound 6’,7’-dihydroxybergamottin, is believed to be responsible for the grapefruit juice effect in which the consumption of the juice affects the metabolism of a variety of pharmaceutical drugs.[19] [edit] Skin care
Bergamot is used in many skin care creams and lotions which harness its cooling, refreshing nature. Bergamot is ideally suited to help calm inflamed skin, and as such is contained in some creams for skin conditions such as psoriasis.[20] It also has antiseptic properties which help ward off infection and aid recovery.
In the past, psoralen extracted from bergamot oil has been used in tanning accelerators and sunscreens. Psoralens penetrate the skin, where they increase the amount of direct DNA damage. This damage is responsible for sunburn and for an increased melanin production. It can also lead to phytophotodermatitis, a darkening of the skin as a result of a chemical reaction that makes the skin extra sensitive to ultraviolet light.
These substances were known to be photocarcinogenic since 1959,[21] but they were only banned from sunscreens in 1995.[22] These photocarcinogenic substances were banned years after they had caused many cases of malignant melanoma and deaths.[23] Psoralen is now used only in the treatment of certain skin disorders, as part of PUVA therapy."
