Pine heartwood features unheard of and so far largely unexploited health-promoting properties. The tree itself but also insects, bees and birds use this effect quite naturally. Swiss researchers were able to prove that ants defend themselves by means of small resin lumps against bacteria and fungi, thus significantly increasing their survival rate.
Songbirds and bees use this potency by sealing their nests with resin compound to protect themselves from diseases. So, it seems quite natural to utilize this potency also for other animals.
Pine heartwood absorbs bacteria and kills them. Fast and thoroughly. That is a natural process which the tree has tried and perfected over millions of years in order to survive. This effect is the basis of all our products for animals.
