I am sure you only used a little oregano oil and did not bath in it, only a KING culd afford such an amount of rare herb and to bath in it would mean instant death.
The added circulation and vapors breathed in enabled things to be excreted or maybe they just had to RUN OUT of you!!!!!!!!!!!!!!!!!!
You know those butt pictures that are expelling globbs of Ascaris worms, the old Amish healer uses my pure oregano in drops in high dose with Amish men/boys and has seen those exact pictures at his clinic. NEVER EVER under estimate the use of spices! The Longevity Spices 4 Life formula is EXTREMELY boosted with powerful spices, yet covered up to taste not so bad, but to worms "they" can not live in the presence of such spices and the ultimate goal is to be wormfree for life.
I would suggest you just expelled pin worms or something else that the body was glad to get rid of.
