Side effects associated with macadamia
Not everything in the world is in perfect uniform. Just like any other product, the macadamia nut oil may not be suited for everyone. Obviously those with nut allergies should stay far away from these products, or at the least consult a doctor to let them know of any experimentation beforehand. There have even been some rare cases of allergies being discovered as result of using the oils.
While the nuts themselves are typically safe to eat, there are many unknown factors yet with strong medicinal use of the oil during pregnancy or breast feeding. This is something else that should be reviewed with the doctor to make sure no harm is done to the mother or the child.
