Horsfield's fruit bat Horsfield's fruit bat Horsfield's fruit bat ("Cynopterus horsfieldii") is a species of megabat native to South East Asia. It is named for Thomas Horsfield, an American naturalist who presented the type specimen to the British Museum. Horsfield's fruit bat is a medium-sized megabat, intermediate in size between flying foxes and pygmy fruit bats. Adults weigh around , and have light-grey to brown fur, with a reddish-brown or orange mantle around the shoulders. In some males, the mantle extends across the chest, and the fur is often brighter in colour than in females. The rim of the ears and the skin
Bergamot orange skin of guinea pigs 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). 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 litres of Earl Grey tea per day (which contains bergamot essential oil as a flavouring) suffered muscle cramps. Bergamot is also a source of bergamottin which, along with the chemically related compound 6',7'-dihydroxybergamottin, is believed to be responsible
