Types of CBD Oil
Until additional studies are complete, it may be a good idea to avoid vaping CBD oil.
CBD oil is a relatively new option to treat asthma as more people are turning to natural treatment options for health conditions.
A subsequent 2019 study published in the “European Journal of Pharmacology” found that CBD reduces airway inflammation and fibrosis in mice with allergic asthma. Further, the anti-inflammatory properties of cannabis may be useful in treating asthma. Researchers who had previously shown that CBD administered to mice prior to a lung injury reduced inflammation also examined the effect of CBD given after the injury. They found that CBD had “a potent anti-inflammatory effect” and improved lung function.
Is Miceli’s success with CBD oil to treat asthma surprising to medical professionals? That depends on who you ask.
Asthma is a condition that most sufferers learn to manage over time, through lifestyle and environmental changes as well as prescription maintenance medication and rescue inhalers for asthma attacks. Nick Foster is an author and blogger who writes about methods for controlling asthma. On his blog Treating Asthma at Home, Foster writes that his asthma was mostly controlled by diet and exercise, but he still felt symptoms and discomfort occasionally so he decided to try CBD. After taking 20 milligrams a day sublingually or orally, he blogged about the results. “I’ve been taking CBD for about a year now, and I still haven’t had to sit through any discomfort or other asthmatic symptoms, let alone use my rescue inhaler,” Foster said.
