I read the following on a credible medical website and applied it to my loss is smell and taste. The operating concept is to stimulate the nerves to recover. It was recommended to apply a sm amount of flavors such as citrus juice, cinnamon, etc to your tongue at least every 4 hrs while awake. Also, inhale individual fragrances + odors up each nostril which I did in between. I used peppermint oil, lavender and other essential oils. I gradually regained full + accurate senses of the taste + smell.
