What is Tung Seed?

Tung seed is the seed of the fruit produced by the tung tree. Tung seeds resemble walnuts, and the term "walnut" is applied to this species. But be very careful not to confuse tung seed with the common walnut. Unlike walnuts, tung seeds are extremely poisonous, even deadly, if they are eaten raw.

Despite these serious safety concerns, people use the oil and the kernels of tung seed to make medicine.

People take tung seed for asthma and bowel problems such as diarrhea and constipation.

Tung seed is sometimes applied to the scalp to encourage hair growth.

In manufacturing, the oil of tung seed is used in soaps, rubber substitutes, linoleum, and insulation. The seed cake of tung seed is used as a fertilizer. The seed is also the source of the oil that is widely used as a wood preservative and varnish.
