A Thought on the holistic tincturing of oleo-resins.
Each type of Oleo-Gum-Resin such as Myrrh, Opoponax, Mastic, the many types of Frankincense etc., contain different proportions of water-soluble gum and alcohol soluble oleo-resins, (resins and volatile oils).
I propose that when one of these Oleo-gum-resins is tinctured to extract its medicinal constituents and properties, that the 2 solvents used for tincturing, be in the same ratio to each other, as the ratio of gum to oleo-resins in the material being tinctured.
In a traditional medicinal, water/alcohol tincture, the gums are dissolved by the water, the oleo resins by the ethanol,(alcohol). What is left over after this extraction is mainly bark and other insoluble extraneous organic material. (Spagyric tinctures often put this to good use). The point of tincturing is to extract as much of the soluble active medicinal components as possible. Ideally exhausting the material by transferring all its chemical constituents to the medicine, while preserving any preexisting synergistic effects between them.
Considering that all parts of these natural Oleo-Gum-Resin exudates, (saps), contain valuable chemical constituents and compounds, and if there is no reason to isolate or change the natural composition of the material, it would be a more efficacious medicine if preserved as close to its natural state as possible
I propose that the best way to create a water/alcohol tincture that is true to its source material, is by using the same ratio of water to ethanol as the plant material exhibits in its ratio of gum to oleo-resin. That this is the only way to accurately migrate the whole material authentically, with its inherent medicinal potency, and any “synergy” that is naturally present in the original material.
Thus, if a sample of Myrrh oleo-gum-resin contains 60% gum and 40% oleo-resins, and a Tincture was made using 100% ethanol, it would only extract the resins and volatile oils. It would have a negligible amount of water-soluble gum. Certainly nothing close to the gum to oleo-resin proportions found in the original material. One would assume this extraction would not offer the same medicinal effects as the whole oleo-gum-resin. 1- Because the water-soluble gum contains chemical constituents that have medicinal value on their own. And 2- because whatever effects the synergy of the whole material had in its natural form, would be lost.
According to this method, a solvent mix composed of 20% alcohol and 80% water would not extract a tincture that was representative of the original material either. Rather it would contain more gum than oleo-resins than the original Myrrh. The same could be said of any other combination of these two solvents other than a combination of water to alcohol that reflected as closely as possible the actual proportions of gum to oleo-resin found in the material tinctured.
Some types of Frankincense contain very little gum, such as Boswellia Frereana. As low as 0. 5%-0.1%, see AritiHerbal table of Extractability of Boswellia Resin. Other types of Frankincense have greater proportions of gum to oleo-resin. According to this theory of holistic tincturing, the unique qualities inherent in each oleo-gum-resin, can only be reproduced in a tincture if the natural ratio of gum to oleo resin in the source material is reflected accurately in the ratio of water to alcohol in the tincturing solvent. One could assume it would keep the same natural synergy in the original material intact by keeping all the chemical constituents in the same relative proportion to each other in the finished product or tincture.
I am not a trained scientist, nor do I have access to the instruments that would put this theory of holistic tincturing to the test. I don’t know if this makes sense to anyone besides myself, or if there is any corroborating research out there to support this theory, but I would Love to hear any opinions, conflicting or supporting.
As an addendum ,( written a month or two after this post), I need to add that after thought, contemplation, examination and the occasional dream, I realize there may be one other way to extract all of the essential oils, resin and gum from these oleo-gum resins. The one way they could be extracted in their entirety and with their naturally occurring proportions intact, without a knowledge of their inherent gum-resin-oil ratios is, If a “disproportionately large” amount of alcohol/water is used for the extraction. So instead of making a 1:5 or 1:6 tincture with 1 being the oleo-gum-resin, something like a 1:10 tincture could be prepared. using much more water than the quantity of gum required, and much more alcohol than the oleo-resin required. In this way all the components could be extracted. However…the obvious drawback, is that there would be a much higher quantity of liquid and a lower proportion of oleo-gum-resin. So it can be done, but with a price. In a way, cheating a bit. This 1:10 ratio tincture, though containing all the soluble and desired parts of the material, would be very weak, which is not ideal and I see no finesse, or advantage to it. It would be very very difficult, if even possible, to remove the excess solvents without losing some of the volatile oils.
Since I am on the topic I will take this opportunity to raise a point that I will address in greater detail in a future post. Lately there has been a lot of talk about the healing properties of Boswellic acid found in Boswellia Sacra. Though much important research has been done on the different types of Frankincense, and Boswellic acid does show great promise as an anti-inflammatory and antitumor, among other important applications, it is not a volatile or essential oil . Which means little, if any Boswellic acid is found in the essential oil of Boswellia Sacra/Carterii. Whatever Boswellic acid is present in the oleo-gum-resins of some of the members of the Boswellia family, resides in the resin part, not in the “Oil”, and is not normally extracted with the essential oils. If a company claims that its essential oil of Frankincense Sacra has a “high percentage of Boswellic acid, then one should ask, how did it get there??
Food for thought.
