Rhubarb, Heart Risk, and the Appendix Nobody Warned You About


Listen Later

This episode covers three new studies: a 2026 trial on a rhubarb root extract for perimenopausal migraines, a Chinese study linking a metric called the Cardiometabolic Index to coronary artery disease severity in menopausal women, and a case report on appendix endometriosis that doubles as a reminder of how badly the medical system underestimates this disease. Research credibility lens throughout, with a hard take on the endometriosis case and what it says about diagnostic culture.
Key Takeaways:
• ERr 731, a standardized extract from rhubarb root, showed statistically significant reductions in headache and migraine frequency in perimenopausal women in a 2026 study — but the trial is small and the funding source warrants scrutiny before drawing strong conclusions.
• The Cardiometabolic Index (CMI) — a ratio derived from waist circumference, height, and blood triglycerides — correlated with both the presence and severity of coronary artery disease in a study of menopausal women, and may be a more accessible screening signal than some current clinical tools.
• Endometriosis can occur in the appendix, and when it does, it can present as acute appendicitis — the 2026 case report involved a postmenopausal woman, a reminder that endometriosis does not reliably stop at menopause.
• Appendix endometriosis is almost never diagnosed before surgery; the diagnosis is typically made by pathology after the appendix is removed.
• The endometriosis case highlights a persistent gap: when women present with acute abdominal pain, endometriosis often isn't on the differential — and that's a clinical culture problem, not just a knowledge gap.
