The Department of Medical Sciences said that extracts from local cannabis strains have been found in a lab that can suppress cancer cells.
He extracted tetrahydrocannabinol (THC) and hemp (CBD) compounds from four local strains of cannabis for testing against cells of seven types of cancer: breast, kidney, liver, lung, intestine, brain and pancreas, said Dr.
While THC is responsible for the high euphoria associated with marijuana, it can relieve pain and nausea, reduce inflammation, and act as an antioxidant. On the other hand, CBD can counteract the high caused by THC but also reduce anxiety, cramping, pain and insomnia.
The team extracted the oil from the flowers and seeds of four local strains – Hang Suea Sakon Nakhon TT 1, Tanaosi Kan Khao WUA 1 (both strains are high in THC), Hang Krarok Phu Phan ST 1, which contains equal levels of THC and CBD and Tanaosi Kan Daeng RD 1, which contains a high level of CBD.
The first test used one dose of THC oil and six doses of CBD oil. Proved to be effective in suppressing cells associated with breast, kidney and liver cancer.
The second test combined 10 doses of THC oil with one dose of CBD oil. This was found to inhibit the growth of cancer cells associated with lung, bowel, brain and pancreatic cancer.
A third test mixed two doses of oil with a high concentration of THC with one dose of CBD oil. The results indicated that this could be used to suppress cancer cells in general.
Dr Subakit said the research showed that hemp oil does not cause bacterial mutations but can be toxic to kidney, liver and lung cells. This discovery was published in the department’s journal, explaining its medicinal effects and toxicity.
The department will continue its animal research and clinical trials.
