The present invention provides cannabis oil extracts and compositions thereof, including cannabis oil compositions containing vitamin E, and methods for preparing the extracts and compositions. In some embodiments, the present invention provides a method for preparing a cannabis oil extract comprising eluting cannabinoids from cannabis plant material with a solvent to produce an eluate, filtering the eluate with a filter to produce a filtrate, evaporating the solvent from the filtrate with a distiller to produce a distillate, and purging the distillate under conditions sufficient to remove residual solvent, thereby preparing the extract. In some embodiments, the method further includes mixing a quantity of vitamin E with the extract to produce a cannabis oil composition.

Cannabidiol (CBD) is one of the most abundant and physiologically active phytocannabinoids in Cannabis plants. The chemical has well-known mechanisms that have been the potential to treat and prevent numerous inflammatory, immunologic, anti-infectious, sun-damaged, age-related (wrinkling, drying, hair loss), and neurogenic-related (anti-pain, anti-itch) diseases as well as heal traumatized skin. The incorporation of CBD on or within topically applied formulations or within wound care dressings, biomaterials skin substitutes, or skin adhesives is a novel approach to alleviate, prevent and cure acute and chronic skin disease, and promote normal healing and recovery after injury.

An improved process for producing various types of cannabis extract from harvested cannabis wherein a quantity of harvested cannabis, which typically includes the inflorescence, floral leaves, and small stems of a flowering cannabis plants, is frozen and subjected to cryogenic grinding to produce pulverized cannabis. The pulverized cannabis is then subjected to alcohol extraction to produce an initial cannabis extract which is filtered to yield a remainder fraction and a filtrate. The remainder fraction potentiates the activity of cannabis formulations while the filtrate can be subjected to one of several forms of further processing according to the desired chemical profile of the final product.

The invention relates to novel genetically modified plants and methods or materials, such as polynucleotides, expression cassettes, or vectors for producing the same. Moreover, the invention relates to altering the content of cannabinoids in plants and to medical compositions derived from such plants. In particular embodiments, the present invention relates to cannabis plants having modified expression of tetrahydrocannabinolic acid (THCA) synthase and methods of modifying the amount of delta-9-tetrahydrocannabinol (THC) and cannabidiol (CBD) in cannabis by modifying expression of THCA synthase.

The present invention may be one of several formulations containing cannabinoids and non-cannabinoid compounds. Cannabis plants are subjected to extraction, and the resulting extract may be supplemented with additional ingredients to achieve a desired chemical profile. Dose titration may be used to find an appropriate dose of Cannabis extract to be ingested in treating medical conditions.

Provided are a method of preparing a cannabis processed product having an increased CBD content in an efficient and economic manner, through decarboxylic acid reaction by microwave irradiation of cannabis using various extraction solvents, and use of the processed product having an increased CBD content prepared by the method, a fraction thereof, and a single ingredient of CBD, in foods, drugs, and cosmetics.

A method and apparatus for pasteurizing and drying cannabis plant materials using a microwave-vacuum chamber. The pasteurizing and drying are carried out with no use of ionizing radiation and with rapid drying. Pasteurization is done at a temperature and for a time period that are sufficient to reduce microorganisms to an acceptably low level, while not significantly reducing the psychoactive compounds in the material. In the process, the pressure inside a vacuum chamber is reduced to a first pressure less than atmospheric. The material is maintained in the vacuum chamber at the first pressure at a pasteurizing temperature while irradiating the material with microwave radiation. The pressure is then reduced to a second pressure lower than the first pressure and the material is maintained in the vacuum chamber at the second pressure for a time period at a dehydrating temperature lower than the pasteurizing temperature while irradiating the material with microwave radiation. The pasteurizing and dehydrating steps can be done in the reverse order.
