Hibiscus Tea, Hormone Balance, and Thrombosis: A Case Report.

An otherwise healthy and active 42-year-old woman, undergoing In-Vitro Fertilization (IVF), developed a deep vein thrombus (a potential side effect of IVF) in her right lower leg after discontinuing the consumption of hibiscus tea. Hibiscus tea contains phytoestrogens which may affect hormone balance - on the one hand reducing the risk of deep vein thrombosis (DVT) and on the other, interfering with the potential success of IVF-related hormone treatments.
