Frozen QWET vs Rosin Yield

From a medicinal standpoint, spectrum being considered, yield being considered. Which has an advantage?

Of course so many subcategories:

Rosin is rosin (depends on press and technique and no solvent)
What i don't have enough data on is the constituent of the rosin like:
1. average total cannabinoid content (ie, are any left out?)
2. average terpene content
3. average flavonoid and other constituents compared to:


QWET
which has many methods within of itself:

Quick Wash Ethanol implies
Frozen Ethanol Extract
(Ethanol = 190 -200 proof food grade alcohol such as everclear, etc.)

Now you can use Fresh Frozen nugs or you can use Frozen nugs
Whatever you do don't do it not frozen, or else you extract too much chlorophyll and undesirables, plant waxes etc. (the green stuff)

Fresh Frozen contains many more terpenes but also more water, so more care is needed to not let it dip below zero degrees.

Now to add to this, you can also do a DRY ICE ETHANOL EXTRACTION

You can add dry ice to ethanol and have it dip below zero degrees celsius.
It will also bubble.
You can then add in your Fresh Frozen nugs and let it soak for a while
You can monitor temps with a temperature gun to see if you are warming up or are too cold possibly (i've heard very cold temps will slow solubility though still looking for that data).and then you can strain and evaporate accordingly.

I find that after evaporation, storing it in a syringe is very convenient for versatility later. Rosin might also be able to achieve this if decarbed and drawn into a syringe for ease of dosing.

For cannabis as an effective medicine, certain conditions need consistent oil ingestion. If a patient can make their medicine at home by pressing their medicine and then possibly decarbing it in an oven as opposed to having to go through the other process, that would be much more convenient and cost effective.

Alcohol has high taxes unless you are distilling it and also doesn't leave behind any usable product per se.
With rosin, you get rosin chips, of which you can create oils, butter and edibles with i would presume. Maybe this oil or butter would be of a more sedative nature.

Yield also is a crucial determinant of what is more cost effective for a medical patient in need.
For example, say you are growing 20% THC cannabis flowers.

Say you press a 100 grams and get a 20% yield from your pressing.

This isn't a guaranteed 20% THC concentrate you are left with. Say you achieved 65% THC as verified by a lab test for your rosin.

If 100 grams yielded 20 grams of Rosin, and of that 20 grams, 65% THC is the result, you are theoretically left with 13 grams of THC in that 20 grams. 8 grams of THC (the other 45%) are in the rosin chips.
And in actuality when comparing the end product of rosin, you are left with usable material which is a plus. You can theoretically take those rosin chips and put them in a slow cooker with coconut oil or ghee and extract what is left. You are using the entire plant in that way.
The rosin chips made into coconut oil probably be more sedative.

Comparing this with QWET extract and yield. Traditionally, as Rick Simpson has wrote in his guide, a pound will yield about 60 grams of oil. That's about a 13.2% return. Already compared to Rosin I'm thinking that it is a lot less (than the achievable 20%).

But see, Ethanol is said to provide a Full Spectrum medicine. Full spectrum doesnt imply chloryphyll either. It implies cannabinoids, terpenes, flavinoids and things of that nature. (non polar in nature).
Doing a cold wash is optimal.
And I can 'see' why it probably is full-spectrum. It's because of the liquid involved, which is able to wash the material and etc. (probably the same reason water hash can yield a nice end product.) you can create a vortex and really mix the stuff and wash off the resins and things on the plant.

let's do the math on that ratio.

If you yield 13.2 percent of oil from ethanol wash...
if you process a 100 grams, that's 13.2 grams of oil
now doing a cold wash, i've heard of extracts being in the 80 - 90% range. I haven't done these tests my self, but let's say we achieve 80% THC in this extract
Our starting herb has 20% per 100 grams
We were able to yield 13.2 grams of oil at an 80% THC content

80% THC of 13.2 grams is 10.56 grams of THC

we are just using THC as a reference and trying to keep everything equal between the two tests:

So in this imaginary experiment from anecdotal evidence found on the net:

RSO yields 10.5 grams of THC from the 13.2 grams from the 100 grams
assuming our RSO had 80% THC

and

Rosin yields 13 grams of THC in that 20 grams from the 100 grams
assuming our rosin had 65% THC


Many questions arise though:


What is in the other 20% in the ethanol (in the form of terpenes, cannabinoids, etc.)
and what is in the other 35% of the rosin (in the form of terpenes, cannabinoids, etc.)

Other things worth considering:

  1. What are the costs associated over time?
  2. What are the dangers associated with performing the extraction?
  3. How long does the extraction take?
  4. Which one provides the most effective full spectrum medicine (with no chlorophyll)

Well I can answer #4. If you press rosin dry, there really is no green and you can still have usable material left over ( no solvent, a bigger upfront cost for a quality press, mostly natural minus bleach on parchment paper or similar concerns.)

there is a consensus in the community that ethanol provides full spectrum benefits.
i am not arguing with it, bc i know from experience that a QWET provides a nice colored (amber) extract and the benefits are solid. i haven't tried ingesting rosin however.

if rosin yields that much more though and provides same or similar effects, it would be worth switiching over.

I havent yet tried the dry ice ethanol extraction method mentioned, thogh it may be worth it, even if it is to throw a few chunks in here and there to keep the termperatures down during extraction.

rosin is faster, cleaner, more environmentally friendly, potentially healthier and more fun. though i haven't tried to ingest it like RSO.

i have heard of people ingesting bho into capsules. I would really just like to know the difference between what is extracted and what is not between Rosin and FROZEN ethanol extraction without having to purchase everything, complete it myself and then have it lab tested. Though just might have to do that.

Holy first novel Batman! :)

I just got out of the hospital after a week so it's too much for me right now. I'll watch the thread and get back to you.

Hahahaha thanks @OldMedUser @charface..... well, after materializing all of these thought, it helped me to realize that it is all good medicine with each method having their slight differences.... what's important is that there are no extremely poisonous or carcinogenic solvents involved or a chance for traces of it to be left over in it....
speculating about what they might do and how they help folks is a good first step, and can even prove those numbers with lab tests and etc to quantify an extractions' constituents etc. But when all is said and done, every patient has to try the medicine for a few weeks or so to gauge how they are doing and how it reacts with their own body chemistry.
Strain plays a huge role... It's not just about the numbers (percentages of constituents and etc), it's not just THC or CBD.. just like it's not just 1 extraction method as the panacea for all types of folks. It's always about the various combinations and then finding the correct combination that complements ones' body chemistry. We are all the same yet we are all different at the same time... Numbers and labs are important though what a particular strain excels at treating I believe is even more key.
So to conclude... full - plant, full - spectrum should be considered first. Non - poisonous / non carcinogenic solvents is right up there along with importance of whole plant (minus polar constituents)... Then pairing specific strains and species with specific ailments. Then the next step would be to figure out which extraction method will complement that person's chemistry through some trial and error. Then, document the results, possibly put into a database, examine the data for very obvious patterns and help others with the information.. rinse and repeat.... Nature just keeps on giving, she is the best.:peace:

Totally agree. My favourite way to ingest my medicine is using cannabis infused coconut oil that has liquid sunflower lecithin added to aid in absorption. I found some info on another forum about "Fresh Harvest Infused Cannabis Oil" where you take it straight off the plant and make what I've been making with cured pot. Anything that cuts down on the amount of trimming my arthritic hands have to do sounds good to me. Google that term and you should be able to easily find it along with links to other threads where some people are doing a lot of the things you lay out in you first post and are getting it lab tested. Why repeat ongoing work when you could read about those and find tangents that you may want to explore based on their efforts and maybe add useful insights of your own.
