A very wise Doctor in South America sends a very nice newsletter telling of the importance of minerals and Ph balance etc. Simple things for health. Here is an exerpt from his recent news that contains “dosages” of baking soda for colds and flu- these were published back in 1925 by Arm and Hammer Company.

My guess is that these would still hold true. Combine the soda with some essential oils like Thieves, Lemon, RC, Exodus II, etc. if you want to be more secure. And don’t forget the Thieves home and hand products!

 
In today’s modern world of medicine the FDA just will not let companies that sell products make medical claims about them unless they have been tested at great expense and approved as a drug. But this was not always the case and as we can see in the information in this chapter, which is from a 1924 booklet,[1] published by the Arm & Hammer Soda Company. On page 12 the company starts off saying, “The proven value of Arm & Hammer Bicarbonate of Soda as a therapeutic agent is further evinced by the following evidence of a prominent physician named Dr. Volney S. Cheney, in a letter to the Church & Dwight Company:
“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.”
Recommended dosages from the Arm and Hammer Company for colds and influenza back in 1925 were:
During the first day take six doses of half teaspoonful of Arm & Hammer Bicarbonate of Soda in glass of cool water, at about two hour intervals.

During the second day take four doses of half teaspoonful of Arm and Hammer Bicarbonate of Soda in glass of cool water, at the same intervals.

During the third day take two doses of half teaspoonful of Arm and Hammer Bicarbonate of Soda in glass of cool water morning and evening, and thereafter half teaspoonful in glass of cool water each morning until cold is cured.
