I'm on one medication that forbids grapefruit, Eliquis, tends to be heart related medication also.Before consuming grapefruit you should check with your pharmacist. Grapefruit is contraindicated when taking some medications.
Google saying "Grapefruit contains a compound known as furanocoumarin, which deactivates an enzyme that breaks down certain drugs, including statins. As a result, the drug concentration increases dramatically. This can cause a rare but serious condition that causes breakdown of muscle tissue and can lead to kidney failure."
Pity as we were given a couple of the yellow grapefruit and I cannot touch them. I really like them as well, one of the fruit I grew up with way back then.
