You can do OP while taking Antibiotics but it would be best if you could decrease and ultimately discontinue them.

When you feel ready, you could ultimately replace them with natural Antibiotics like garlic, echinacea, green foods and supplements, etc. Immune-boosting teas like Gypsy Cold Care would be good too. Those items would be compatible with OP.

Having had respiratory problems since being a kid I've had to take massive amounts of Antibiotics throughout my life. Several years ago I completely gave them up to natural Antibiotics .

When I get sick now (which I do much less often) I'll oil pull with 4-5 drops of oregano oil in my other oil (usually flax seed) 3 times a day. In addition, I'll gargle with Colloidal Silver , and also spray it in my ears and nose. I seem to get over bronchitis now in 3-4 days instead of the weeks it took with anti-biotics.

When it gets really bad (borderline pneumonia), I also inhale a combination of Colloidal Silver and lobella through a nebulizer. Also Holy Basil tea works well for bronchitis, etc.
