Nut Allergies

As the source of tung oil is a nut, people with nut allergies have reported adverse reactions to contact with (or even the odour of) tung oil. Reactions can be severe in some cases.

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, some individuals must avoid its use.
