Review (1/5): Is it old, oxidized  oil or not cured properly?
This tamanu oil is black which might mean that the tamanu nuts were thrown into the fire to speed up the curing process rather than letting them dry naturally on racks for 1-2 months. The black color could also mean that this oil is old and oxidized. Tamanu oil is supposed to be dark green NOT black! So many supposed tamanu oils are mixed with other carrier oils so that the tamanu is diluted and not offering the full benefits of this wonderful skin oil. Or, the tamanu nuts are not cured properly which also changes the benefits of properly cured, 100% tamanu oil. So buyer beware, do some research and try to find 100% tamanu oil that is dark green in color so that you get 100% of the full benefit this oil offers. This brand of tamanu makes me wonder if I'm getting any of the benefits tamanu brings like helping prevent wrinkles or helping reduce symptoms of psoriasis, etc.
