A wide variety of solvents can be used for extraction, such as chloroform, dichloromethane, petroleum ether, naphtha, benzene, butane, methanol, ethanol, isopropanol, and olive oil. Currently, resinoids are often obtained by extraction with supercritical carbon dioxide. The alcohols extract undesirable water-soluble substances such as chlorophylls and sugars (which can be removed later by washing with water). Non-polar solvents such as benzene, chloroform and petroleum ether will not extract the water-soluble constituents of marijuana or hashish while still producing hash oil. In general, non-polar cannabis extracts taste much better than polar extracts. Alkali washing further improves the odor and taste.
In addition to the well-known activity on CB1 and CB2 receptors, there is further evidence that CBD also activates 5-HT1A/2A/3A serotonergic and TRPV1–2 vanilloid receptors, antagonizes alpha-1 adrenergic and µ-opioid receptors, inhibits synaptosomal uptake of noradrenaline, dopamine, serotonin and gamma-aminobutyric acid (GABA), and cellular uptake of anandamide, acts on mitochondria Ca2+ stores, blocks low-voltage-activated (T-type) Ca2+ channels, stimulates activity of the inhibitory glycine-receptor, and inhibits activity of fatty amide hydrolase (FAAH) [1, 2].
Schizophrenia. Research on the use of cannabidiol for psychotic symptoms in people with schizophrenia is conflicting. Some early research suggests that taking cannabidiol four times daily for 4 weeks improves psychotic symptoms and might be as effective as the antipsychotic medication amisulpride. However, other early research suggests that taking cannabidiol for 14 days is not beneficial. The conflicting results might be related to the cannabidiol dose used and duration of treatment.
Laboratory evidence indicated that cannabidiol may reduce THC clearance, increasing plasma concentrations which may raise THC availability to receptors and enhance its effect in a dose-dependent manner. In vitro, cannabidiol inhibited receptors affecting the activity of voltage-dependent sodium and potassium channels, which may affect neural activity. A small clinical trial reported that CBD partially inhibited the CYP2C-catalyzed hydroxylation of THC to 11-OH-THC.
It should also be noted that, because CBD oil is mostly unregulated, products may be incorrectly labeled. To that end, a study published in the Journal of the American Medical Association in 2017 found that nearly 70 percent of all CBD products sold online are mislabeled and that a number of products contain a significant amount of THC. Since THC can aggravate anxiety and make your heart beat faster than normal, it’s possible that using CBD oil that contains THC might make your anxiety worse.
The oil may be further refined by 1) alkali washing, or removing the heavy aromatic carboxylic acids with antibiotic properties, which may cause heartburn, gallbladder and pancreas irritation, and resistance to hemp antibiotics; 2) conversion of CBD to THC. Process 1) consists of dissolving the oil in a nonpolar solvent such as petroleum ether, repeatedly washing (saponifying) with a base such as sodium carbonate solution until the yellow residue disappears from the watery phase, decanting, and washing with water to remove the base and the saponified components (and evaporating the solvents). This process reduces the oil yield, but the resulting oil is less acidic, easier digestible and much more potent (almost pure THC). Process 2) consists of dissolving the oil in a suitable solvent such as absolute ethanol containing 0.05% hydrochloric acid, and boiling the mixture for 2 hours.
The rosemary acts as a natural antioxidant preservative. It also supplies terpenoids, including camphene, pinene, and limonene, that support a healthy inflammatory response and promote relaxation.* Hops is a very close cousin of hemp and many of the compounds in hops are complementary to those in hemp. The hops in Hemp Oil + provides a source of the terpenoids humulon and lupulon that are synergistic with the phytocannabinoids in support of the ECS.*
Serotonin: Most people associate serotonin with happiness. However, the role of this neurotransmitter is very complex, and its effects depend on where it is and what it binds to. (Contrary to popular belief, more serotonin is not necessarily better — dysfunction can stem from low or high levels of serotonin, as well as from malfunctions with their receptors.) Serotonin has at least 14 different receptors, but CBD specifically binds to 5-HT1A which is thought to have the strongest role in anxiety disorders. The anti-anxiety drug buspirone also binds to this particular receptor, which explains the anti-anxiety effects of CBD on rats exposed to stressful situations.

One of the most popular and well-known uses of pure cannabis essential oil is to get relief from stress and anxiety, according to a report published in the Journal of Cannabis Therapeutics. The natural compounds found in this oil, including the famed THC, which is what gives cannabis the distinction of a drug in many countries, are very good for releasing pleasure hormones and relaxing the mind. It also helps in reducing stress and inducing a sense of calmness and relaxation.
One of the most profound uses of cannabidiol oil is for the relief of arthritic pain. There are two kinds of arthritis, rheumatoid and osteoarthritis, both resulting in swelling and stiffness in joints. Scientific studies have documented that the application of CBD oil can help assuage the pain caused by inflammations. Results have been encouraging. Health associations and the government, alike, are optimistic about the role of CBD oil in bringing solace to arthritic patients.
Although cannabidiol still requires further study to know all of its health benefits, scientists have been able to pinpoint some of the medical uses of the compound. CBD can help treat nausea and vomiting, making it a useful choice for cancer patients. Cannabidiol may also help shrink the growth of cancer and tumors. It may help people who suffer from psychoses, anxiety and depression. Inflammation and neurodegenerative effects, such as those with Alzheimer’s disease, may be reduced through the use of CBD. Oil made from the compound could even be used to treat forms of epilepsy in children. Its calming effects are also useful for people with social anxiety disorder.
Marijuana can produce acute psychotic episodes at high doses, and several studies have linked marijuana use to increased risk for chronic psychosis in individuals with specific genetic risk factors. Research suggests that these effects are mediated by THC, and it has been suggested that CBD may mitigate these effects.xxxi There have been a few small-scale clinical trials in which patients with psychotic symptoms were treated with CBD, including case reports of patients with schizophrenia that reported conflicting results; a small case study in patients with Parkinson’s disease with psychosis, which reported positive results; and one small randomized clinical trial reporting clinical improvement in patients with schizophrenia treated with CBD.xxxii Large randomized clinical trials would be needed to fully evaluate the therapeutic potential of CBD for patients with schizophrenia and other forms of psychosis.
