Hi, thanks,
yes it is product with many uses, and only now i read a bit more about its uses from the site to which the instruction-page linked.
It seems there could be some good info for you too but oh my the quality of google translate seems to be quite bad.. but maybe with good will and imagination or with some help of proper dictionary its possible to get the point in the sentences anyway.
Interesting that you study Finnish culture,, where do you study it?
For sure yeah the soldiers could very well have made tar in the forests as it used to be much commonly known skill before, to make tar.
Old saying in Finland says that "ellei sauna, viina ja terva auta, tauti on kuolemaksi"-> "if sauna, alcohol and tar does not help, the sickness is going to lead to death".
This short saying means practically that in the old times, pine tar - diluted to alcohol and mixed with
water, then thrown on the sauna-stones was used as very common and effective medicine for many kinds of sicknesses,, together for sure with plants collected from nature and set into sauna in water to purify and also to "hitting" the patient with them while bathing in hot steam. Mostly small branches of birch were used, but different plants have different properties...
I haven't used tar so much in sauna (or for buildings, boats etc either), but since I was child, we always used to have a jar of
honey, into which small amount of tar has been mixed and this honey&tar is super medicine to generally enhance the immunity.
If one is sensitive to perceive the bio-energy fields in nature and around living things, it can be clearly seen/perceived that the field of bio-energy the honey has, multiplies greatly when mixing a little bit of tar into it. I think honey has such effect to many medicines,, like if you mix for example ginger into honey (or a bit of honey to strong ginger tea), the properties of ginger get also stronger and so on..
