Printed in the 1850 edition’s “A List of the Principal Diseases” as “—— (palpitation of)” under “Heart-Burn” (the dash stands for the heading above it, or its first word); shown here as “Heart (palpitation of)”.
Modern literature has not yet been searched for this heading’s claims: it comes only from the 1850 index and has no search words yet.
Old claims, quoted verbatim: not medical advice. A warning sits above the claims and never hides them; no warning does not mean safe, only that no source here has flagged the plant.
1 claim: 0 with a sentence, 1 from the index alone
