Isopropyl alcohol and its link to cancer.

[mexcurandero420]

Not to mention a host for cancer if the chemicals aren't purged fully even so, trace elements will last and show up.

In the vid he was using Naphta, but a purified one, still this isn't used in pharmaceutical herb extraction.Iso can affect your nerve system, happend with a guy in the Netherlands.

Sir William O’Shaughnessy: The Grandfather of Medical Cannabis

https://www.compassionatecertificat...ughnessy-the-grandfather-of-medical-cannabis/

By Heather Ritchie, Staff Writer for Terpenes and Testing Magazine


Most medical cannabis patients may not be familiar with Dr. William Brooke O’Shaughnessy who introduced the herb to contemporary Western Medicine. Not only was he a pioneer of cannabis therapy, but he also “invented the modern treatment for cholera, laid the first telegraph system in Asia, and made significant contributions to pharmacology, chemistry, drug clinical trials, science education, and underwater engineering.” He was more productive in his lifetime than some inventors combined. Let’s see how O’Shaughnessy effectively changed the world.

Born a poor Irish kid in Limerick during 1809, (Some information suggests that he may actually have been born in late 1808.) he showed such remarkable intelligence that he was admitted into the University of Edinburgh in 1827. As part of the lower class and hardly 18 years of age, his admittance into the best medical school in the world was unusual.

He studied chemistry, medicine, anatomy, and forensic toxicology. After teaching for awhile when he graduated, he started a forensic toxicology lab in London, doing chemical analysis on things like urine and blood for courts, hospitals, and doctors.

In 1831, a cholera outbreak led him to analyze the blood of those affected by the illness. Though it wouldn’t be identified as vibrio cholerae until 1883, he identified the treatment as intravenous fluid intervention that helped alleviate dehydration. The doctors who tested this theory saved the lives of almost half of their patients which was some feat back then!
Cannabis in India


O’Shaughnessy spent two different periods of his life in India. One was from 1833-1841 and the other 1852-1860. During his first trip, he tested the medicinal properties of indigenous plants like cannabis and opium.

Understanding that cannabis and other plants were used recreationally and medicinally in the area for thousands of years, he focused on the therapeutic effects of cannabis. Western medicine had no literature on these properties. He noted how the indigenous people prepared edibles and drinks with cannabis.

Wanting to test the locals’ claims about cannabis, he started a broad range of experiments on animals and moved to human research after he saw that cannabis was safe. He studied the effect cannabis had on diseases like hydrophobia, rabies, infant convulsions, cholera, tetanus, and rheumatism and eventually presented his research to the Medical and Physical Society of Calcutta in 1839.

The results showed that cannabis weren’t necessarily a “cure all” for ailments, but rather a beneficial treatment because of its calming and pain-relieving effects. He noticed it also quelled muscle spasms from rabies and tetanus.

Today we know that medical cannabis patients use the herb to ease spasms associated with conditions like dystonia, motor neuron disease, and multiple sclerosis. It’s also become an accepted medicinal treatment in conditions like epilepsy. O’ Shaughnessy also studied cannabis use as an anesthetic and severe pain relief.
Introducing England to Cannabis


After publishing several books, he took a leave of absence to return home to England in 1841 and brought back hemp for the Pharmaceutical Society and “Nux vomica” and “Cannabis indica” for the Royal Botanical Gardens at Kew. Chemists made potent extracts and tinctures with O’ Shaughnessy’s recipes. Queen Victoria’s personal physician advocated for its use in patients to ease menstrual cramps on the advice of O’Shaughnessy, and as a result, in 1848 he was elected a Fellow of the Royal Society.

In 1842 he published The Bengal Dispensatory and in 1844, The Bengal Pharmacopeia about some of India’s plants. The section on cannabis was 25 pages and was described by James Mills in the Cannabis Britannica as, “the most comprehensive assessment of the properties of cannabis.”
The Creator of the First Telegraph Circuit


Aside from cannabis, O’Shaughnessy was also well-known for his work on the telegraph. He experimented with creating the first telegraph circuit at the Botanical Gardens in Shibpur. He laid cables with the two ends starting and ending with his position. Then he used a pair of inexpensive, modified watches to successfully transmit messages. In 1838, he proceeded on to experiment in sending electrical signals under Calcutta’s River Hooghly through insulated iron wires. It was the first successful underwater telegraphy ever.

Over the ensuing years, he made history with the scientific advancements of the telegraph after his return to India in 1844. One of his most significant challenges was finding an alternative to the copper wires used in America and England as they were too fragile for India’s environment.

With the political clout of Lord James A. B. Ramsey (Dalhousie), O’Shaughnessy he found a way to simplify the signal transmission process, and in 1857 he invented a cryptographic code for transmitting secret messages. While being knighted in England by Queen Victoria, he met Samuel Morse and other telegraph experts which probably paved the way for the cryptographic code invention.

After mutineers destroyed telegraph lines in India, he went back to train his replacements and supervise the rebuilding project. He left India to return to London for the last time in 1860.
Mystery-What Happened to William O’Shaughnessy


Once back in London, he divorced his wife suddenly and married Julia Greenly. He changed his name to Sir William O’Shaughnessy Brooke, possibly to gain favor for an inheritance from his family on the Brooke side.

Next, he disappeared. No one knows what he did in the years before he died in 1889. A doctor that thought William was a member of the Indo-European Telegraph Company believed that he might have traveled with them as a line-laying expert in difficult terrains, specifically underwater.

No matter how he lived out his last years, his reputation as scholar and inventor long outlived him. O’Shaughnessy’s scientific capability as a scientist is the reason that he had such a profound impact on cannabis research. Many think he is, indeed, the grandfather of medical cannabis research.

thanks @ Gry , that´s really interesting stuff, very informative. He was certainly very productive, wasn´t he. I´ve always been interested in invention-stuff so this was nice to read

 

[Douglas.Curtis]

Sam says he's never tested an iso extract (even washed and purged) which tested negative for iso. I'm sure a great many of them were made with 99% iso. Personally, I get a raw throat and lungs after vaping iso anything for a week. Additional downsides are cumulative tissue damage and organ damage, also possible links to reproductive harm.

Ethanol is good, CO2 works very well.

Howdy, This book was published by 'Dr' Hulda Clark who has been thoroughly discredited for this work. She was summarily kicked out of Mexico for practicing her 'medicine'. That says it all being Mexico is quite dubious for medical practitioners. Her work was so bad, the Mexican Govt didn't put up with it. You cannot quote anything she says, as it go 180 degrees against science.

So, start over. Find another voice that supports legitimate science. She was selling a little device that with a turn of the knobs shows you the product is cancerous. Oh, BTW, Isopropyl is not cancerous or it would be an FDA Class 1 compound. Its not toxic like Methanol or it would be a FDA Class 2 compound. Its listed right along side Ethanol as a FDA Class 3 compound not known for everything you are fearing here.

BTW, did you know your liver breaks Isopropyl down in to Acetone? Did you know your liver produces Acetone when it breaks down lipids? Acetone is a Ketone which is used for energy or expelled via urine or exhailing. Your body knows how to deal with it, in small qualities. On the other hand, Ethanol is a known damager of your DNA. Your liver breaks down Ethanol into Acetadehyde, a know carcinogen. This is why alcohol is damaging over the long run. It takes years of damage to accumulate as it happens very slowly.

So, all that to say, don't take Urban Legend for fact. If someone says something like this, have them back it up with molecular science, because the science says something completely different that 'Dr' Hulda Clark.

Here's Wikpedia's bio on Dr Hulda Clark.

I mean lab tests show pretty clearly whether a product is purged of excess solvents.
there are people who produce clean product and people who don’t.
I wouldn’t throw the baby out with the bath water... just my opinion.. I do prefer rosin to any solvent produced hash but idk if I can jump on board the all solvent based hash has adulterants.
also I was under the impression that rso called for the use of naptha (basically paint thinner)... perhaps I am recalling it wrong

yes you are right on the naptha!

 

[Gray Wolf]

yes you are right on the naptha!

Rick started with Naptha, which is not a specific product, but a boiling point range, that unfortunately includes Benzene. He and I actually discussed that issue on a radio talk show back in the day.

In pharmaceutical terms, the poison is in the dosage. Substances that are salubrious or curative at low dosages become pernicious at higher dosages, sooo one way to alleviate concerns about toxicity, is to purge the solvent below the levels of concern.

The FDA classifies Propanol 2 or Isopropyl, as Class 3 solvents, with the residual solvent standards as follows:

Note that Class 3 includes solvents like acetic acid (vinegar) ethanol, pentane, and 2-Propanol (Isopropyl) and that the residual standards are 50 mg per day or less, 5000ppm residual, or 0.5%.


Isopropyl alcohol is a pungent alcohol that our smell and taste senses can detect at around 7.8 mg/M3, or about 3.7 ppm, so if you can no longer smell or taste it, it is below 1% of FDA limits.

Solvents in Class 3 (Table 3) may be regarded as less toxic and of lower risk to human health.

Class 3 includes no solvent known as a human health hazard at levels normally accepted in pharmaceuticals. However, there are no long-term toxicity or carcinogenicity studies for many of the solvents in Class 3.

Available data indicate that they are less toxic in acute or short-term studies and negative in genotoxicity studies. It is considered that amounts of these residual solvents of 50 mg per day or less (corresponding to 5,000 ppm or 0.5 percent under Option 1) would be acceptable without justification.

Higher amounts may also be acceptable provided they are realistic in relation to manufacturing capability and good manufacturing practice (GMP).

Table 3. – Class 3 Solvents include Acetic acid, Heptane, Acetone, Isobutyl acetate, Anisole, Isopropyl acetate, 1-Butanol, Methyl acetate, 2-Butanol, 3-Methyl-1-butanol, Butyl acetate, Methylethyl ketone, tert-Butylmethyl ether, Methylisobutyl ketone, Dimethyl sulfoxide, 2-Methyl-1-propanol, Ethanol, Pentane, Ethyl acetate, 1-Pentanol, Ethyl ether, 1-Propanol, Ethyl formate, 2-Propanol, Formic acid, & Propyl acetate.
