I am doing research on mosquito repellent as a part of my college project. I have found various sources of marigold being used as insect repellent such as the following link- https://www.ncbi.nlm.nih.gov/pmc/articles/PMC3385578/
I have not seen use of marigold in commercial mosquito repellent. Can marigold extract be used in mosquito repellent ointment? Any help would be appreciated.
