Medicinal Properties of Frog's Blood?

Factual Questions
1

I am transcribing the memoirs of a gg-aunt who lived in Alabama in the early 1900s.

She wrote, “I had scarlet fever while living there and almost died. My throat had to be lanced twice. Once, Dr. Stephens had Mama go into the garden, which was back of the house, and get a toad frog and cut it open, and when he lanced my throat he put it on it while the frog was still warm and bound it on. My throat got well then.” ???

Any clues on how the the frog’s blood could have counteracted the fever?

Not making this up…

“put it on it while the frog was still warm”

Now it gets warm in Alabama, but for a frog to be noticeably warm to an ill child it would need to be about 110o where the frog was caught.

I think your aunt may be misremembering events. That doesn’t make the rest of the story very credible.
