Claims in a 1924 ad:
“In 1918 and 1919 while fighting the ‘Flu’ with the U. S. Public Health Service it was brought to my attention that rarely any one who had been thoroughly alkalinized with bicarbonate of soda contracted the disease, and those who did contract it, if alkalinized early, would invariably have mild attacks. I have since that time treated all cases of ‘Cold,’ Influenza and LaGripe by first giving generous doses of Bicarbonate of Soda, and in many, many instances within 36 hours the symptoms would have entirely abated. Further, within my own household, before Woman’s Clubs and Parent-Teachers’ Associations, I have advocated the use of Bicarbonate of Soda as a preventive for “Colds,” with the result that now many reports are coming in stating that those who took “Soda” were not affected, while nearly every one around them had the “Flu.”
In order to secure the best results with Arm & Hammer Pure Bicarbonate of Soda (Baking Soda) when taken internally, certain simple rules must be observed. Materia Medica, pharmacology and Therapeutics (Bastedo, Page 88) clearly outlines these rules to follows:
“The effect of an alkali in the stomach will vary according to the nature of the stomach contents at the time of administration. In the resting period (after food is digested) sodium bicarbonate merely dissolves mucus and is absorbed as bicarbonate into the blood, to increase its alkalinity directly.
“In the digestive period it reduces the secretion of gastric juice, neutralizes a portion of the hydrochloric acid, liberates the carminative carbon dioxide gas, and is absorbed as sodium chloride.
“In cases of fermentation or ‘sour stomach’ it may neutralize the organic acids and so result in the opening of a spasmodically closed pylorus (the opening between the stomach and the small intestine); while at the same time it acts to overcome flatulency (accumulation of gas in the stomach and bowels).
“The time of administration must, therefore, be chosen with a definite purpose. Usually for hyperchlohydria (excess of acid) one hour or two hours after meals will be the period of harmful excess of acid.
“In continuous hyperacidity and in fermentative conditions a dose an hour before meals will tend to prepare the stomach for the next meal; or sometimes a dose will be necessary immediately after eating, because of abnormal acid or base having been present at the commencement of the meal. (For the average person one-half hour after meals is recommended).
