I do not believe in mercury, arsenic, and the host of mineral poisons which are found in so many remedies. When taken into the system they disturb every function, interfere with the most vital processes, and produce the most disastrous consequences. =The Purest and Best.=--Knowing these things, Mrs. Pinkham was exceedingly careful to put only the purest and choicest of products of the vegetable kingdom into her Compound. Each of the roots and herbs is selected with the most extreme care, and all are prepared under the personal supervision of the most thoroughly trained specialists. =One Secret.=--One great secret of the success of Lydia E. Pinkham's Vegetable Compound is that each vegetable is so treated that all useful elements are retained, and all useless discarded. =Highly Concentrated.=--For instance, it is possible for the expert workmen in our laboratory to condense all the medicinal power that exists in a pound of the coarse root into a mass no larger than could be held on the point of a knife. In this way it is possible for a teaspoonful of the Vegetable Compound to represent all the curative properties usually found in eight or ten times that quantity; in other words, it is highly concentrated. =Acts Upon Female Organs.=--Mrs. Pinkham knew from the very first that she was on the right track. She knew that her Vegetable Compound contained medicines which act directly and naturally upon the female organs. She knew that one ingredient produced certain effects on the uterus, while other ingredients tended to relieve pain in the ovaries. She knew that one remedy would heal an inflamed uterine cavity, while another ingredient would cause better circulation in the blood-vessels of this part of the body. Having the theory all worked out most carefully, she awaited the practical test, feeling confident as to the result. =Success Was Immediate.=--But she did not have to wait long. Immediately the cures began, and her neighbors and friends told each other what had been done for them. Soon letters came by the hundreds from all parts of the world. Thousands upon thousands have written to Mrs. Pinkham telling her their story, and giving to her, also, full permission to use their testimonials. =It Bridges the Gulf.=--I am sure you would be delighted, as well as surprised, if you could see the immense difference between the first and last letters received from women. The first is the story of suffering, of extreme agony with prolonged misery and abandoned hope. The last is a song of gratitude, of great love, of joy and peace. The first tells of disease, the last of health. But what an immense gulf between these two!--a gulf, however, I am glad to say, that can be bridged with Lydia E. Pinkham's Vegetable Compound.
