Acute disease reaction: quick and easy if given soon after onset. More reaction if many days pass. A slight aggravation in a few minutes means you will probably not have to give another dose.
Chronic disease, long standing illness, or physical change reaction: sharp aggravations, great prostration, violent sweating, exhaustion, vomiting and purging. Some reactions may not be able to be recovered from. Sometimes no aggravation if there has been no tissue changes. The repair of diseased tissue will cause great discomfort but must not be suppressed by another remedy.
A disease picture may be a shadow of the disease to come and a remedy may pull it out of the shadows and show itself as an aggravation. A remedy can not give symptoms to a person that they don't have unless they are very sensitive people.
Begin cases without repetition. Give a single dose and wait, and watch its effects. There are no good rules for when to repeat the dose.
A quick reaction means that you should wait as long as you see the remedy working before giving another dose. Falling asleep, breaking out in sweat or mental calmness means wait and be patient. A continued disease state or a vigorous constitution allows more repetition.
The strength of the remedy should be strong enough or similar enough to produce just enough aggravation so you know that the curative effect will cover all of the disease state. If you have no aggravation you will most likely have to repeat the dose or find a closer remedy. Sometimes several remedies will be necessary to complete the case. Again sensitive people will aggravate easily.
