The honey murcott's are great, super sweet when ripe but heaps of seeds and hard to peel, I make the kids eat em on the grass. Mine gets a massive crop every second season, the cockatoo's love them too, and my previous bully used to roll them out with her nose and eat all the flesh leaving just the skin. Lime tree fruits most of the year, and the grapefruit (was supposed to be a ruby but it's not ) gets fruit fly sometimes but heaps of fruit. Love marmalade so use some for that.
With respect to the drug interactions, grapefruit suppresses the absorption of some drugs, but also effects an enzyme in the SI that breaks some other drugs down, thereby causing a higher/longer concentration in the blood stream of some drugs too. @ 100 drugs are effected by grapefruit.
My son and I piss on the citrus when the missus aint around.
