When making herbal preparations, one adds a solvent, usually alcohol; and leaves it to soak. After a soaking period (usually 6 to 8 weeks) sufficient medicinal properties are transferred to the solvent, to extract the 'medicine' from the herbs. This is usually done by filtering out the herb, and disposing of what's left.
Here is one such herbal:
)
This is Arnica, which can not be taken internally! Since it can't be ingested, this is made with isopropanol alcohol; which makes a liniment, to be applied externally for pain reduction.
Here is a method where we can continue to soak the herbs, for increased strength:
)
To remove the herb flowers from the extracted fluid, I put a large syringe (60ml) down the center of the jar, which fills with clear liquid. Note, I had to cut off the end of the syringe to reduce the length, so it will fit.
Then I insert a smaller syringe:
)
Which is then filled with the clear fluid, while allowing the herb flowers to continue to soak in the solvent.
This allows me to get STRONGER Arnica liniment than most people, by the extended soaking time!
So my liniment is strong enough to be dark green:
)
My apologies, the flash makes this liniment look brown, but it's actually green. This does at least show how strong the solution actually is.
This is the Arnica in a roller bottle:
)
The flash is still on here, so it still looks brown. But it shows how strong the solution is becoming. The next Jar is processing now, but won't be tapped, until this jar is empty.
Here is the solution without the flash:
)
Now you can see the correct color, noting that most Arnica liniment has little or no color. This works better than the pre-filtered style Arnica liniment, because it has more Arnica in the solution!
This also works with tinctures, which saves filtering, and yields stronger 💊💉 medicines.
We must study, and rely on ourselves, because western medicine continues to degrade, and is slowly failing! I don't say this to scare you, by rather to motivate you. Herbals, used properly, can effectively replace the doctor's visits; and return healthy bodies to those peppers willing to study!
