Eh. I don't have to. It's basic science. If you read about IBS, you will find that different patients respond to different dietary regimes. All of them are told to increase fiber intake but the problem is that there are no specifics given because nothing works for everyone. Eating lentil helps a lot but I got tired of making soup daily, so I had to look elsewhere since other vegetables and fruits didn't have a similar effect. However, the fibers in unprocessed cocoa powder is equally effective in my case. So I switched my daily cup of coffe with a cup of cocoa. Pills no more!

As for Ponaris, few drops in each nostril will create a physical barrier preventing allergens from sticking to the insides of the nasal walls preventing your body from reacting to them in the first place, it will lock the moisture in dry weather conditions. You can't use any oil on the shelf though, just the ones that are processed in a way that it would cause no problems if small amounts make it your lungs. Ponaris is prescribed by some doctors, some doctors told me to use vaseline in a similar fashion for the same basic concept I explained earlier.

Of course you have to prove it! Its fundamentally not science if you cannot prove it!

If its basic science it should be even easier to prove. Go ahead then. Put up or shut up.

I told you to read about IBS because it's easy to find out that fibers is the best thing you can do to keep symptoms at bay. In my case, lentil and cocoa work the best. Read here about the role of fibers in managing IBS on the official NHS website:

As for controlling allergies, the concept is simple, don't let the allergens in. You can do that by wearing a mask, staying indoors, or rubbing a bit vaseline or oil inside your nose, whatever suits you!

"NHS Choices suggests you rub Vaseline just inside your nostrils to keep pollen out"

My favorite oil, as a man, is Shutran. It is called beard oil and pretty much every man who has it on is irresistable to women. Every girl I've ever heard talk about this oil pretty much dies when their man puts it on; my own wife as well. Aside from being appealing to the womenfolk, it makes your skin a lot less itchy under your beard (a problem I have a lot with my dry skin).

And where do either of these recommend essential oils? Ohh right. They don't. I guess that isn't actually the evidence I asked for.

I specifically talked about Ponaris and cocoa in my original post and not anything else. Just substitute cocoa with "fibers" (because it has fibers in it, like most plant-based food) and Ponaris with vaseline because they work similarly, they are not "drugs" but they create a barrier that traps pollen and locks in the moist.

Ponaris is sold in pharmacies and was recommended to me by my doctor when I told him that "vaseline is effective but it SUCKS to have it inside my nose"
