Vaping Herbs For A Non Smoker??

I do not smoke or drink. But i do use herbs like peppermint and Tulsi. But most herbs upset my stomach, since I had acid reflux surgery. I have read that vaping is harmful to the lung and others that say it is good. But this is mainly for smokers and used as an alternative. I have clear lungs, but want to vape herbal remedies to improve my health.

Has anyone seen a benefit in vaping even if they never smoked?? Is it harmful to the lungs, though I know it it not harmful like smoking? I want to improve my health and I am hoping I can vape herbal remedies safely??

anyone??
