Linseed oil comes from seeds of the toxic Flax plant (Linum usitatissimum). Linseed oil, or Flax seed oil, has much special traditional uses in medicine, fabric, wood polish and plaster.

Spun flax resembles blond hair and the plant grows pretty looking flowers from vivid blue to scarlet colours.

In mythology, Flax is a herb potent to maternal goddesses, especially Frigga and Holda, associated with spinning.
Despite it's magical properties, linseed oil is dangerous. King Tutankhamun's remains were slowly burned after mummification. A TV documentary called "Tutankhamun: Mystery of the Burnt Mummy" explored this subject and found that the linen had to have been drenched in linseed oil to cause spontaneous combustion. An experiment was done to show this. It demonstrated how cloth soaked in linseed oil cooked itself at a certain room temperature alone without any fire. It reveals the power of linseed oil.
