Although only a few clinical studies have been conducted, basic research, suggests therapeutic potential in a variety of diseases such as schizophrenia, epilepsy, and skin diseases as well as various other symptoms. Cannabinoids, including cannabidiol, are powerful antioxidants. In addition, CBD has anxiolytic and powerful anti-inflammatory properties.

Cannabidiol also inhibits ID protein, which plays an important role in tumor biology. CBD is thus the first exogenous non-toxic substance to reduce the ID1-expression in breast cancer cells and lead to a decrease in tumor aggressiveness.
According to research at the California Pacific Medical Center Research Institute in San Francisco, CBD increases the inhibitory effects of dronabinol (THC) on human brain cancer cell proliferation and cell survival. The two natural cannabinoids have been tested on two series of glioblastoma cells. THC and CBD had a synergistic inhibitory effect on cell proliferation.
Other research groups have confirmed the anti-cancer effects of CBD in glioma and leukemia cells. In leukemia research, a combination of several cannabinoids also increased the effect against cancer. The lead researcher said: “These agents are able to interfere with the development of cancer cells, stopping and preventing them from growing. In some cases, they can destroy cancer cells alone in compliance with specific dosage regimens. In combination with existing treatments, they could possibly constitute very effective strategies for fighting cancer.”

According to a study published in 2007, all cannabinoids – THC, CBD, CBN, CBG and anandamide – proved to be effective in inhibiting the production of keratinocytes in the epidermis; and since in psoriasis it’s about an overproduction of keratinocytes, these findings will prove to be helpful in future research on cannabinoid therapies to treat the disease.
CBD has also proven its therapeutic benefits for treating acne. Administering Cannabidiol to cultured human sebocytes and human skin organ cultures inhibited the lipogenic effects of various compounds, including arachidonic acid and a combination made from linoleic acid and testosterone. It also suppresses the sebocyte proliferation by activating the transient receptor potential of vanilloid-4 (TRPV4) ion channels.
The study concludes: “In summary, our findings suggest that CBD has the potential to be a promising therapeutic agent for treating acne vulgaris based on its combined lipostatic, anti-proliferative and anti-inflammatory effects.”

If the body is not in a position to effectively detoxify these ROS, then the oxidative stress may increase until apoptosis (cell death) sets in. Oxidative stress is involved in the development of various progressive diseases such as Alzheimer’s, Parkinson’s, Fragile X syndrome and cancer. Normal cells require low concentrations of ROS to make a healthy transfer of cellular signals possible. If the fragile cells in question are cancerous, they need a high concentration of ROS in order to maintain higher metabolism rates and increasing division and growth rates. Therefore, oxidative stress generally promotes the growth of cancer cells. However, it was proven that the oxidative stress generated by CBD in certain cancer cell types can actually initiate apoptosis, particularly in breast cancer in humans.
