Okay.
The cheapest essential oil is fir oil. There is plenty of raw material, and it is easy to obtain.
That is why the oil is cheap—and at the same time very powerful.
I will not even mention that walking through spruce forests improves your health... everyone knows that.
Of course, fir oil is nowhere near as pleasant as, for example, genuine lavender essential oil.
Do not be fooled into thinking it smells like a spruce forest
I have this oil, and I recommend buying it from only one place because it is tested there. As far as I understood, it is made either by Old Believers or by pagan Slavic Ingliists... In any case, that is not so important.
The products are environmentally clean, from the taiga. That is what matters.
The fir essence is also carefully extracted, without chemicals.
It costs literally pennies for a rather large bottle:
Fir oil, 100 ml.
I also recommend buying fir balm there:
Fir balm, 250 g.
It also removes all sorts of filth from the body.
Fir essential oil and fir balm work very well together.
There is also black cumin oil; it is simply vegetable oil, not essential oil:
Black cumin oil, 100 ml
It is good in the mornings. It also fights parasites.
I have already talked many times about resin on the Your Yoga website.
It is available there too, from Siberia.
As for worldwide delivery, I cannot say anything. You will have to arrange that.
I also cannot say anything about buying other oils. I have not even tried buying any others.
This can also be used internally.
Fir balm has an effect similar to Citrosept. It may even be more powerful.
Simply dilute a teaspoon in warm water.
If you persist for long enough, you can remove all the filth from your body using only these remedies.
But as I said, the ether is not limited to this alone.
