Simple quick de-worm tricks.
If this is still a problem, do this and your worms and their eggs will die--from tongue, mouth, nasal cavity, lungs and brain:
a little eucalyptus oil right on that 'canker sore,' also behind each ear along lymph glands and in armpit lymph nodes...
chew some organic whole cloves (mine are from Sri Lanka; you can buy a few bulk from a natural foods co-op or order some) and inhale thru your mouth (and the clove fumes which are like a wonderful stinging fire)...
HOLD your breath, filling your nasal cavities and lungs, then release slowly thru the nose.
Fresh clove will clean yer clock--and clean out the worms & eggs also.
Sleep w/ eucalyptus drops on your pillow and rubbed on foot soles, clove fumes still in your mouth and dreams of the garlic you'll smoke 'em out with tomorrow.
These things clear your brain fog in short order, send dozens of thread worms out of your nose in quick gusher nose bleeds (examine the clots--the long thin thread worms quickly stand out), clear your lungs, make breathing a joy again like being a kid,
AND get rid of belly bloat, make you feel light and free (tho' very tired and sleepy initially as you clean 'em out) and restore your volition to exert and do, protect the planet, seek the mystery of God and love your enemy. No need for docs and Big Pharm & big cost!
May the Lord bless you and keep you!
