The following may or may not help:
Two drops of Frankincense under your tongue, morning and night.
Make sure it is pure oil. There are three different types: Sartori, Carterii, and Sacred.
I use Carterii, but only two drops under my tongue, per day (because I have not been diagnosed with anything). I can't afford Sacred or I would use that.
I only came to this because my brother was diagnosed with pancreatic cancer and I was trying to help him. He passed away a year ago January.
I do the two drops morning and night when I feel I'm coming down with something, otherwise it's just two drops a day as a regimen.
I haven't been sick or even had a head cold since I started. I was too late to save my brother.
