Star Fruit has a neurotoxin. It shouldn't be fed to animals or people with questionable kidneys, and shouldn't EVER be juiced and drank by healthy people.

Eating the fruit in regular amounts is fine if you're healthy, but juicing a dozen into a glass can be dangerous.
It also interferes with drug absorption (similar to grapefruit). So if you're on an Rx that tells you to avoid grapefruit, avoid star fruit too.
Risks
Carambolas contains caramboxin[11] and oxalic acid. Both substances are harmful to individuals suffering from kidney failure, kidney stones, or those under kidney dialysis treatment. Consumption by those with kidney failure can produce hiccups, vomiting, nausea, mental confusion, and sometimes death.[12][13][14][15][16][17] Recent research has identified caramboxin as a neurotoxin which is structurally similar to phenylalanine, and is a glutamatergic agonist.[11] Despite its toxicity to renally-compromised individuals, the levels of oxalic acid and caramboxin in starfruit are low enough to be safely processed by the general population, for whom it is both a safe and healthy food.
Drug interactions
Like the grapefruit, carambola is considered to be a potent inhibitor of seven cytochrome P450 isoforms.[18][19] These enzymes are significant in the first-pass elimination of many medicines, and, thus, the consumption of carambola or its juice in combination with certain prescription medications can significantly increase their effective dosage within the body. Research into grapefruit juice (its potent enzymes) for instance, identified a significant effect (requires change in dose or other side effects) on common medications when taken concurrently by the patient, including statins, which are commonly used to treat high cholesterol and cardiovascular illness, opiates/opioids, and benzodiazepines (a sedative tranquilizer drug family that includes diazepam).[20]
