Baryta muriatica [Bar-m]
Dr. A.L. Blackwood says that wherever there is very high blood pressure Baryta mur. 6x will give relief. This does not apply to cases where the pressure results from diseased kidneys or calcareous blood vessels, but in otherwise apparently normal persons.
He found the 3x rather aggravated the trouble, but the 6x generally acted like a charm. Those who were given the 3x said, I cannot stand that medicine, but those receiving the 6x expressed great relief, all of which seems to show that the potencies play an important part in really scientific medicine. Too much may be hurtful, when enough is curative. Better sin on the side of the small dose. Strychnine will kill; it will also cure-in the small dose. So it is rational medicine not to get as close as you can to the killing dose, but as far as you can from it to still keep to the curative dose. In these Radium days, and X-ray days, this curative stage is very far from the killing dose.
