This is an excerpt of something I just posted. It's from the Oil Pulling booklet I found online. Hope this answers some of your questions.
Are there any adverse reactions with OP?
Dr Karach said: “some people in whom various illnesses are simultaneously manifest, an
apparent worsening of condition is possible. This is due to primary infection first being depleted,
causing secondary infections to dominate temporarily. After a few days secondary infection will
disappear while another may be stimulated into activity. Such symptoms are usually apparent in
persons suffering from chronic or terminal illnesses. Under these circumstances Dr Karach
recommends that the affected person steadfastly continues the treatment even if fevers are
initiated. Dr Karach maintains just when these symptoms appear the oil treatment will facilitate
rapid healing. Should the treatment be broken for one reason or another the overall effects will be
slowed down. For these reasons Dr Karach maintains that an apparent worsening of health is an
excellent sign that disease is progressively being removed from the body”.
Examples: To cite examples: - (a) Itching of the skin during infection and inflammation of an
injury or wound and the same itching may be present in an aggravated manner during cure of the
wound/injury. (b) A bone breaks due to an accident. The pain at the time of setting is more severe
and also during the process of healing.
Advice on how to deal with healing reactions
• Do OP as usual or increase to two or three times a day or even stop for a few days
depending on the severity and your reaction.
• Take medicine under the advice of a doctor for a minimum period, for relief and continue
OP after the reactions is over.
• It is not necessary that there will be healing reactions for all cases. Most of the cases are
chronic and the patient has been suffering for long and possibly under treatment. Healing
reaction appears more severe and one gets the feeling that disease is aggravating. At
such time one is inclined to stop OP, do not stop but continue OP. This is a sure sign
before cure. Recognize it as a reaction and continue OP and you will be cured with in a
short time and you will know the state of disease free health which makes you happy.
