Cannabidiol, or CBD, is a compound found in the Cannabis Sativa plant, which includes both hemp and marijuana. Unlike its cousin compound, delta-9-tetrahydrocannabinol (THC), CBD does not have psychoactive effects, meaning it does not cause a “high”[1][6]. CBD oil is a product that contains concentrations of CBD, and its use has surged in recent years due to its potential therapeutic benefits and the growing acceptance of cannabis-based products.
Extraction Process
CBD oil is primarily extracted from industrial hemp, a variety of the Cannabis Sativa plant that is low in THC content[1]. There are several methods of extracting CBD from hemp, but the most common ones are Soxhlet extraction, maceration, and ultrasound-assisted extraction[2].
Soxhlet extraction and maceration are traditional methods that require longer extraction times and large amounts of solvent. In contrast, ultrasound-assisted extraction is a more modern technique that can significantly speed up the process and potentially improve the yield of CBD[2][7].
In the ultrasound-assisted extraction process, fresh hemp is subjected to ultrasonic waves, which help to break down the plant cell walls and facilitate the release of CBD into the solvent. This method has been found to be efficient and fast, providing equivalent CBD content in a shorter time compared to traditional methods[7].
Health Benefits and Uses in Medicine
CBD oil is used as a specific therapy for multiple diverse medical conditions, particularly pain, anxiety, depression, and sleep disorders[1]. Research has shown that CBD may have antidepressant-like activity, and its effects may depend on the activation of certain receptors in the brain[1].
In addition to mental health conditions, CBD oil has also shown promise in the treatment of certain physical conditions. For example, a single dose of CBD has been found to reduce blood pressure in healthy volunteers[1]. Furthermore, understanding of CBD’s efficacy and safety in the treatment of epilepsy has expanded significantly in recent years[1].
Despite these potential benefits, it’s important to note that CBD oil is not a cure-all. While it may help alleviate symptoms of certain conditions, it should not replace traditional medical treatments unless advised by a healthcare provider[3].
Australian Law
In Australia, the use of medicinal cannabis and CBD oil is continuing to propagate, with increasing numbers of patients and practitioners wanting to learn more and obtain access[4]. However, the regulatory and legal framework for its therapeutic use in Australia is complex and evolving.
As of now, CBD oil is considered a controlled substance under Australian law, and its use requires a prescription from a registered Australian doctor. The doctor must be authorized by the Therapeutic Goods Administration (TGA) to prescribe medicinal cannabis products[4].
Summing Up
CBD oil is a promising therapeutic agent with potential benefits for a range of medical conditions. However, more research is needed to fully understand its effects and optimal usage. As the legal landscape continues to evolve, it’s important for consumers and healthcare providers to stay informed about the latest research and regulations regarding CBD oil.
