Can relieve pain

As early as 2900 BC, cannabis was used to treat pain . Recently, scientists have discovered that certain components of cannabis, including CBD, are responsible for its analgesic effects. The human body contains a specialized system called the endocannabinoid system (ECS), which is involved in regulating multiple functions, including sleep, appetite, pain, and immune system response. The body produces endocannabinoids, which are neurotransmitters that bind to cannabinoid receptors in the nervous system. Studies have shown that CBD may help reduce chronic pain by affecting the activity of endocannabinoid receptors, reducing inflammation, and interacting with neurotransmitters.

For example, a rat study found that CBD injection reduced the pain response to surgical incisions, while another rat study found that oral CBD treatment significantly reduced sciatic nerve pain and inflammation. Several human studies have found that the combination of CBD and THC can effectively treat the pain associated with multiple sclerosis and arthritis.

An oral spray called Sativex is a combination of THC and CBD and has been approved in many countries for the treatment of pain associated with multiple sclerosis. A study of 47 patients with multiple sclerosis examined the effects of taking Sativex for one month. Participants improved in pain, walking, and muscle cramps. Nevertheless, the study did not include any control group, and the placebo effect cannot be ruled out . Another study found that Sativex significantly improved exercise pain, rest pain, and sleep quality in 58 patients with rheumatoid arthritis.

Can reduce anxiety and depression

Anxiety and depression are common mental health disorders that can have devastating effects on health and well-being. According to data from the World Health Organization, depression is the single largest cause of disability globally, while anxiety is ranked sixth. Anxiety and depression are usually treated with medications, which can cause many side effects, including drowsiness, agitation, insomnia, sexual dysfunction, and headaches. More importantly, benzodiazepines can be addictive and can lead to drug abuse .

CBD oil has shown promise as a treatment for depression and anxiety, leading many people suffering from these diseases to be interested in this natural method. In a study in Brazil, 57 men received oral CBD or a placebo 90 minutes before taking the mock public speaking test. Researchers found that a 300 mg dose of CBD was the most effective in significantly reducing anxiety during the test. Placebo, 150 mg of CBD and 600 mg of CBD had little effect on anxiety. CBD oil has even been used to safely treat insomnia and anxiety in children suffering from post-traumatic stress disorder. CBD has also shown similar antidepressant effects in several animal studies. These qualities are related to the ability of CBD to act on the brain's serotonin receptors, which is a neurotransmitter that regulates mood and social behavior.

Can relieve cancer-related symptoms

CBD may help reduce cancer-related symptoms and side effects related to cancer treatment, such as nausea, vomiting, and pain. One study looked at the effects of CBD and THC on 177 cancer-related pain patients who were not relieved from analgesics. Compared with patients who received only THC extracts, patients who received extracts containing these two compounds had significantly less pain. CBD may also help reduce nausea and vomiting caused by chemotherapy, which is one of the most common chemotherapy-related side effects in cancer patients. Although there are some medications that can help relieve these distressing symptoms, they are sometimes ineffective, leading some people to seek alternatives. A study of 16 people undergoing chemotherapy found that a one-to-one combination of CBD and THC administered via oral sprays reduced chemotherapy-related nausea and vomiting better than standard treatment alone. Some test tube and animal studies even indicate that CBD may have anti-cancer properties. For example, a test tube study found that concentrated CBD induced cell death in human breast cancer cells. Another study showed that CBD inhibited the spread of aggressive breast cancer cells in mice.
However, these are test tube and animal studies, so they can only suggest methods that may be effective for humans. Before drawing conclusions, more research on humans is needed.

Can reduce acne

Acne is a common skin disease that affects more than 9% of the population . It is believed to be caused by a variety of factors, including genetics, bacteria, potential inflammation, and excessive production of sebum, which is an oily secretion secreted by the sebaceous glands in the skin. According to recent scientific research, CBD oil may help treat acne because of its anti-inflammatory properties and ability to reduce sebum production.

A test tube study found that CBD oil can prevent sebaceous gland cells from secreting excessive sebum, exert anti-inflammatory effects and prevent the activation of inflammatory cytokines and other "acne-promoting" factors. Another study also found similar findings, and concluded that CBD may be an effective and safe treatment for acne, partly due to its excellent anti-inflammatory properties. Although these results are promising, human studies are still needed to explore the effects of CBD on acne.

May have neuroprotective properties

Researchers believe that the ability of CBD to act on the endocannabinoid system and other brain signaling systems may benefit patients with neurological diseases. In fact, one of the most researched uses of CBD is to treat neurological diseases such as epilepsy and multiple sclerosis. Although research in this area is relatively new, some studies have shown promising results.

Sativex is an oral spray composed of CBD and THC, which has been proven to be a safe and effective way to reduce muscle cramps in patients with multiple sclerosis. A study found that Sativex reduced 75% of cramps in 276 patients with multiple sclerosis, whose muscle cramps were resistant to medications.
Another study allowed 214 people with severe epilepsy to consume 0.9-2.3 grams of CBD oil per pound (2-5 g/kg) of body weight. Their seizures were reduced by 36.5% .
Another study found that compared with placebo, CBD oil significantly reduced seizure activity in children with Dravet syndrome, a complex childhood epilepsy.
However, it is worth noting that some people in these two studies experienced adverse reactions related to CBD treatment, such as convulsions, fever, and fatigue. CBD has also been studied for its potential effectiveness in the treatment of several other neurological diseases. For example, some studies have shown that CBD treatment improves the quality of life and sleep quality of Parkinson's disease patients.
In addition, animal and test-tube studies have shown that CBD can reduce inflammation and help prevent neurodegeneration associated with Alzheimer's disease.
In a long-term study, researchers gave CBD to mice with a genetic predisposition for Alzheimer's disease and found that it helps prevent cognitive decline.

Good for heart health

Recent research has linked CBD to several benefits of the heart and circulatory system, including the ability to reduce high blood pressure. Hypertension and high risk of many health-related, including stroke, heart dirty onset of the disease and the metabolic syndrome. Studies have shown that CBD may help treat high blood pressure.

A recent study treated nine healthy men with a 600 mg dose of CBD oil and found that it lowered resting blood pressure compared to a placebo.
The same study also conducted stress tests on men who usually increase blood pressure. Interestingly, in these tests, a single dose of CBD caused men's blood pressure to rise less than normal .
Researchers believe that CBD's properties of reducing stress and anxiety are the reason why it helps lower blood pressure.
In addition, several animal studies have shown that CBD may help reduce inflammation and cell death associated with heart disease because of its powerful antioxidant and stress-reducing properties.
For example, a study found that treatment with CBD can reduce oxidative stress in diabetic mice with heart disease and prevent heart damage.

Several other potential benefits

The role of CBD in the treatment of many health problems in addition to the above-mentioned problems has been studied. Although more research is needed, but the CBD is believed to provide the following health benefits:

psychotic effects: Studies have shown that, CBD can help patients with schizophrenia and other mental disorders by reducing psychotic symptoms.

Drug abuse treatment: CBD has been shown to change the brain circuits related to drug addiction. In rats, CBD has been shown to reduce morphine dependence and heroin seeking behavior.

Anti-tumor effect: CBD has been shown to have anti-tumor effect in test tube and animal studies. In animals, it has been shown to prevent the spread of breast, prostate, brain, colon and lung cancer.

Diabetes prevention: In diabetic mice,
CBD treatment reduced the incidence of diabetes by 56% and significantly reduced inflammation.

are there any side effects?

Although CBD is generally well tolerated and considered safe, it may cause adverse reactions in some people. Side effects noted in the study include:

  • diarrhea
  • Changes in appetite and weight
  • fatigue

As we all know, CBD interacts with a variety of drugs. Before you start using CBD oil, please discuss with your doctor to ensure your safety and avoid potentially harmful interactions .
This is especially important if you are taking medicines or supplements with a "grapefruit warning". Both grapefruit and CBD interfere with cytochrome P450 (CYPs), a group of enzymes that are important for drug metabolism.
A study in mice showed that CBD-rich cannabis extract may cause liver toxicity. However, some mice in the study were forced to feed very large doses of the extract.

in conclusion

CBD has been studied oil potential role in alleviating the symptoms of many common health problems, including anxiety, depression, acne and heart dirty disease. For those suffering from cancer, it can even provide a natural option for pain and symptom relief. Research on the potential health benefits of CBD oil is ongoing, so new therapeutic uses for this natural remedy will definitely be discovered. Although there is still a lot to know about the efficacy and safety of CBD, recent research results show that CBD can provide safe and effective natural remedies for many health problems.

What is cannabidiol (CBD)? What is the difference between cannabidiol, tetrahydrocannabinol (THC) and cannabis?

Cannabis generally refers to the cannabis plant and its live seeds. Cannabis contains a variety of cannabinoids, the most active ones are tetrahydrocannabinol and cannabidiol, both of which can be extracted from the cannabis plant or synthesized artificially. Cannabis, tetrahydrocannabinol and certain cannabinoids have psychoactive effects and have the risk of being used as drugs for abuse, which can be addictive and harmful to health. Cannabis, cannabis resin, tetrahydrocannabinol and certain other cannabinoids are all dangerous drugs controlled by the Dangerous Drugs Ordinance. Cannabidiol has no psychoactive effects and is not used as a risk of drug abuse. It is not a dangerous drug and is not controlled by the Dangerous Drugs Ordinance. However, according to the Pharmacy and Poisons Ordinance (Chapter 138 of the Laws of Hong Kong) and the "Pharmacy and Poisons Regulations" (Chapter 138A of the Laws of Hong Kong), any pharmaceutical product containing cannabidiol is classified as Part 1 Poison And prescription drugs. The supply and distribution of such prescription drugs are strictly controlled.

There are many types of cannabidiol products (such as food, beverages and skin care products). Are these products legal in Hong Kong? Can I purchase or use these products through local or overseas distributors (for example, via the Internet)?

Cannabidiol is different from cannabis or tetrahydrocannabinol. It is not a dangerous drug and is not controlled by the Dangerous Drugs Ordinance.
