I would appreciate the advice about the old wives tale, even if I don't after all use it. I promise to upvote every supportive comment and downvote every mocking comment!
We forgot about it until I was gasping for air and then my wife remembered and we had some laying around. I could breath again in about 20 minutes. My chest and lungs still hurt until today.
I mean, maybe Moringa Oil is amazing (I doubt it). It's available for much cheaper than the listed amazon link: https://www.vitaminshoppe.com/p/cold-pressed-rwandan-moringa...
The price point on amazon is ridiculous though...makes me want to get in the business of packaging and selling this product in the future (not specific to covid).
