When i went to morocco i bought nigella seeds. i was told if you smell them that it will help fight allergies. is that true?

Smell?: I haven't heard of smelling them, but may be behind the curve. Nigella seeds contain thymoquinone, which blocks (likely H2 receptor predominantly) histamine and is shown to activate TRP1 receptors. Notably, azelastine (nasal antihistamine) is effective in part due to activation/desensitization of TRP1 receptors (good for allergic and non-allergic rhinitis). Suspect Nigella acts (see comment)
