    Perhaps start with lower dosages. You don’t say what kind of allergy symptoms. i had hayfever symptoms = sinus leaking and swelling ,puffyness, and itching . i stopped and started again in a week or so. Similar lower grade symptoms.
    A year later i figured the black seed oils was flushing out toxins intwined with cells of skin , sinus, eyes. A fragment of a pebble lodged in my temple kk[from some car passing] slowly started pushing out. Glass stuck in my eye , ever so fragment, arrived at surface and was soon stuck on a fluff of cotton and out of the eye.
    Sore knuckles and sking and waiting on dark hair tho perhaps wouldve went completely siver,
    Found a youtube vid saying make tea out of it. 7 dollars was all the health store had on their quanity shelf. Slowly dried in a hot pan and added water and milk.

    Hope that helps
