1900's health remedy kit

Hello,I'm renovating my home and came across this Health Specialist Sproule three way method remedy kit. I'm assuming it's from the 1900's due to the newspapers we also found and the postage. The kit includes a small glass corked bottle of inhaling solution, a small box of what I believe were pills (look like raisins now), and a small jar of cream or oil to rub on skin. It is in the original box, directions included and original postage on box. I have looked all over online and cannot find any information on it and I'm just curious if it's worth anything? Any feedback would be greatly appreciated. Thank you.Tracey
