Hi , and welcome! I see you have been a member here since early July and, we appreciate your registering with the community. We are glad to see you engaging directly with the community now through this, your first post.
While I am hopeful others in the community will see your question and respond by sharing their own experiences using black seed oil, I have something to add as well. I did a brief search of the literature and was able to find a brief summary article which focused on Black seed oil. For your convenience, here is a link to that material: https://www.ncbi.nlm.nih.gov/pmc/articles/PMC6111118/.
Based on my understanding of the article, it sounds like more extensive research needs to be done to fully evaluate the effects of black seed oil in the treatment of asthma. What do you think?
