If you are adding peels of fruits into this cocktail before consumption, I highly suggest that you scrub & clean the outsides of the fruits thoroughly. Many fruits have pesticides being sprayed on them which is harmful for humans. Apples have wax coating around them so either boil the fruit in hot water or scrape the wax off using a butter knife before using it for cooking or other purposes. Apart from that, since the fruits & spices are from nature & have more health benefits compared to store-bought juices, the cocktail you described seems to be safe.
