An all natural product. Contains only beeswax and pine tar oil.
The smoke from open fires made up with fungi or dry rot protected the aborigines of northern Scandinavia from the mosquito plague. Later "Beckolja" was produced and still later, in the mid 1940s - we got "Djungel Oil".
Nordic Summer is a mixture of the effective ingredients of all these and we use it on our regular and frequent Sweden and Scotland trips.
We have used this product for a decades now and swear by it.
