We recommend that you use the tinctures once opened within 90 days, this doesn't mean that the tinctures will go bad after such period. The best way to know if the oil is good is by smelling it. If it's smells rancid is time to get a new bottle. If the oils is kept in the fridge it will last much longer but is not necessary to do so.
Iceland ‘Pure ONLY uses, fully vertically integrated, US based, 100% federally legal producer and distributor of the highest quality medicinal Cannabis rich CBD hemp in the United States, with practically zero THC. What separates our CBD Source from all of those "hemp oil hustlers", begins with our proprietary medicinal cannabis strain. Our proprietary strain is a hybrid AC/DC x Cannatonic x (another naturally high CBD strain), all of which are known for their medicinal value.
The cross-breeding of this naturally high CBD/low THC strain took place over a seven year period, and was done in order to reduce the amount of naturally occurring THC down to a level that classified it as "industrial hemp" (less than .3%) . While everyone else was cross-breeding their strains to increase the level of THC, we had the foresight to do the complete opposite! CBD isolate and CBD oils are THC free, we achieve this through our proprietary extraction process that incorporates a gas chromatography method, allowing us to identify the naturally occurring THC and separate it out completely, instantly, while leaving intact the other synergistic components of the oil. NOT ALL HEMP IS CREATED EQUAL ... Industrial hemp is genetically inferior to medicinal hemp, yet it is defined the same way by the regulatory agencies. Many brands/companies/legal counsel who still believe that hemp-derived CBD must come from overseas to be "fully legal" are not taking into consideration the 2014 US Farm Bill section 7606 which created for the first time since 1937, a Federally legal pathway to growing "industrial hemp" once again on American soil.
Our sources conforms entirely to section 7606 of the 2014 Farm Bill and our "medicinal hemp" strain is registered with the Colorado State Department of Agriculture as "industrial hemp". As demand for CBD continues to grow, so too will the synthetic forms of CBD crystalline isolate coming out of China and Eastern Europe. Bulk/wholesale CBD buyers need to be cautious when purchasing CBD from overseas, as much of it contains heavy metals, toxins, and/or mysterious chemicals.
True quality control can only be guaranteed if all aspects of the supply chain and manufacturing is vertically-integrated, and that is what our source does.
