Do not try peppers or spices since they harm nasal tissues. They are really very harmful to the nose – not only to tissues, but also to olfactory function. You may lose your sense of smell over time if you regularly use such a method to decongest your nose.
Yes, it’s true that these methods may open the nasal passages very effectively, but this fact doesn’t make them your friends. They open the nose because they irritate the tissues in the nose so much that those tissues (especially the turbinates) shrink to minimize their surface area in contact with the irritating fume or liquid. This shrinkage brings about an open nose through which you can breathe freely. This relief may even last for a few hours if you have tortured your nose enough. But, all these benefits are in exchange for damage to your nasal tissues. Damaged tissues make you more prone to sicknesses and inflammation, which require a regular need for decongestants. If you continue using any of these hazardous decongesting techniques, you’ll find yourself in a vicious cycle, which – if unbroken – will leave you with totally disabled cilia.
Don't let desperation lead you to try things just because someone advises you to do so and never consider peppers and spices as means to decongest your nose.
