Procedure
- Clean the resin of bark and needles; if stiff, let it soften in a warm place.
- In a bowl over a water bath heat oil (olive or sunflower) to 60–70 °C and dissolve the resin in it while stirring; impurities settle or are strained through cloth.
- Add beeswax and stir until dissolved; test the consistency — a drop on a cold saucer should set to a soft salve.
- Pour into clean pots, let it set and label. Use thinly on intact skin.
Extraction
- Herb:
- 1 díl pryskyřice na 4 díly oleje a 1 díl včelího vosku objemově
- Solvent:
- pryskyřice se rozpustí v teplém oleji (60–70 °C), potom vosk
- Shelf life:
- 12 měsíců v chladu a temnu
- Target compounds:
- diterpenové kyseliny a silice (β-pinen, bornylacetát) přecházejí do oleje; vosk dává konzistenci
Notes
An external folk salve for minor scrapes and cracked skin. Resin can cause contact allergy in sensitive people — patch-test a small area first. Not for the eyes, not on open wounds.
Why it works
Fir resin is a mix of diterpene acids and volatile oil that dissolve in oil and, with wax, form a protective film; the balsam's traditional 'healing' reputation has a long history among Indigenous peoples of North America, but clinical proof is lacking.
