Pure Tung Oil is pressed from the seed of the Tung Tree, which is a different botanical family to peanuts and to cashews/pistachios. There is some disagreement about whether it is actually a seed or a nut, so whilst it is possible for someone to be allergic to Tung Oil, it is not known to be associated with any other nut allergies, and so is unlikely to cause a reaction in an individual who has a peanut or tree nut allergy.
Once dry, tung oil is polymerised by reaction with air to a solid, unreactive flexible film, which is classed as food and toy safe.
While tung oil has been used for many centuries as a finish for kitchen items such as wooden bowls and cutting boards, and we are unaware of any known cases of a reaction to tung oil, people with severe allergies or sensitisation should use their usual caution.
