I am copying below a post that I have just read with my response which I believe should be of interest to Homeopaths.

Re: Weight Reduction with Nat Phos 6x. Latest News From libra on 2005-10-13
Hi Joe,

After reading your posts in this forum, I advised my daughter 40 years to take Nat Phos 6x for weight reduction. She inadvertently took Natrum Sulph 6x. In her own words, after half an hour of taking first dose of Natrum Sulph 6x I had a mild attack of Bronchial congestion and cough with burning sensation in the Bronchial tube. When I took second dose after dinner, half an hour thereafter, I again had the above symptoms with greater intensity and in addition some itching in the Bronchial tube, lungs and inside of the back. At this I realized that I was taking wrong medicine. By the next morning all these symptoms subsided. By the way I had these symptoms in my childhood.
I have seen for the first time that a first dose of homeopathic medicine brought out the old symptoms. Will you offer comments on this. Should she take Natrum Sulph 6x for clearing her old symptoms before starting Natrum Phos 6x for weight reduction. Thanks

Nat Sulph 6x taken accidentally From Joe De Livera on 2005-10-13
To Libra

Thank you for having brought the reaction that your daughter had when she took Nat Sulph 6x instead of Nat Phos 6x. The reaction that she had was what is known as Proving the remedy. You may know that Homeopathy was born when Hahnemann discovered that if large doses of Quinine extract were used that symptoms similar to Malaria were noticed with rigors and high temperature.

Your daughter was proving the remedy which I prescribe in almost all cases of Asthma but for this ailment a higher potency of it Nat Sulph 6c is used which is far less a dose when compared with Nat Sulph 6x. The 6x potency is exactly 1/1Millionth of the salt Sodium Sulphate or Glauber's Salt which is a chemical commonly used in the formulation of medical drugs. Nat Sulph 6c is exactly 1 Million Millionth of this salt and it will be observed that it is 1 Million times the dose that your daughter used accidentally. However I am glad to note that no damage was done and I shall remember this news that you were kind enough to record on this forum.

I hope that other Homeopaths will note this phenomenon as this all contributes to the study of Homeopathy. Incidents such as this help us to remember more forcefully that what we have studied in out texts have been formulated by the classical authors after actual tests (provings) were made by them over the past 150 years.

I notice that you have used the first person 'I' to report this case of your daughter who according to you, took the Nat Sulph 6x instead of the Nat Phos 6x by mistake. Please clarify who used the Nat Sulph 6x. You or your daughter ?

There is no need for your daughter to take any medication except the Nat Phos 6x dose 2 tablets after both lunch and dinner, for weight reduction. Please tell her that the taboos of coffee and cold drinks must not be used during treatment as weight reduction does not occur if these taboos are used.

Thank you once again for having brought this accidental use of Nat Sulph 6x instead of Nat Phos 6x to my attention.

Please report your daughter's response to the Nat Phos 6x in a week when you can expect a drop in her weight of at least 1 pound.
