What's the deal with medicated snuff?

I’ve searched around but can’t really find any info. What is it medicating exactly? Is it meant to unclog sinuses or what?

Generally the term “medicated” indicates the use of menthol, eucalyptus and/or camphor as the primary scenting system.  Others include various mints along with these.  It has an immediate sinus clearing effect, but with me, if the menthol is too high I get a backlash that makes the original stuffiness even worse.

I love Dholakia Medicated No. 10 That stuff works . My head was hurting and within a matter of seconds my head felt great. Although regular snuff may had worked to. But the No10 was comforting. I like 6 Photo #66 for the power range of in the middle of 6 and 666.  Dr.Rumney’s 5g In South African snuffs works good. 

Plenty of Indian snuff although not medicated have medical powers to relax or change your disposition. I don’t use medicated snuff until I need to.

Now menthol snuff is a different story. some menthols give me rebound congestion. I prefer non menthol but enjoy some menthol bombs on occasion.I never had a problem with any 6 Photo that has menthol.6 Photo Special is my go to for clearing the sinus. All the Black snuffs work equally. 

 Menthol is addicting Tobacco is addicting to Poschl that means big profits. I determined why Poschl snuffs are weak in nicotine; so you use more. Now that is a solid business plan. I do like some Red Bull and Edel Frucht    

There is one snuff that will work under any circumstance and that is FUBAR Bohica with it’s beautiful chocolate aroma ; grant it you will be cursing bloody hell for the world to hear for a good 20 minutes but it will expel anything in your nose, it may also bring tears to your eyes and sweat to your head it may even turn your face red .
