Beef tea. Mum scraped a knife across uncooked beef and when she had enough fibres, boiled that up with a little water.
Thermogene and Camphorated oil for chests.
Benger's Food if we were really peaky, otherwise Pobs and
an egg beaten up in milk and sieved to get the nasty thick bit of the albumen out. Mum once forgot that and I was sick all over the eiderdown. 
Senna pods or Syrup of Figs if we were constipated and as we got older, Petrolagar.
Germolene for cuts and grazed knees (permanent with me, a tree and wall climber). TCP - hated that smell.
Golden Eye Ointment but also, 'If you pick your nose and then touch your eye, you'll get a sty.'
Something I didn't believe until much later when my doctor auntie told me it was true.
Lucozade was too expensive but Mum made lemonade whenever the fruit was in season and added citric acid, which made it into a dilutable cordial. Yum.
At other times it was Elderberry Cordial, not considered a sovereign remedy.
Elderflower Chanpagne in summer whe the flowers were out but that wasn't medication, it was pure pleasure.
As was Virol which we had every day as a preventative.
Sometimes spread on buttered bread or toast.
