In its normal state it is a boring tree of light, white wood with no fragrance. After attacks by insects or birds or branches broken by wind or rain, sometimes it starts to segregate a resin to cauterize the wounds. This resin spreads through the whole tree in an alquimic process that lasts decades until the wood becomes dark and so heavy that it doesn't float on water. That is why in Japan it is called "jinkoh": wood that sinks. The aloe's fragrance is deep, rich and earthy. A bit spicy and, at the same time, with a balsamic touch.
Doesn't have anything to do with the orange colored fossilized resin of the same name. The amber used in perfumery comes from a kind of whale, the sperm whale. Sperm whales have a highly developed breathing system that lets them dive into the sea depths to hunt giant squids that swallow whole. Those squids have a peak similar to the parrot's one and, so that it doesn't harm it's digestive system, sperm whales segregate a substance that covers it during digestion and that they later expel trough the mouth. This substance is the grey amber.
