Laboratory studies

Some people claim that aloe vera can balance the immune system or even treat and cure cancer. But there is currently no evidence that aloe can treat cancer in humans.

Some laboratory studies and early studies on animals looked at extracts from aloe. It found that it might be helpful in boosting the immune system to attack cancer cells. But researchers have not tested the safety of these chemicals in humans. We don't know whether they may work.

Several studies have looked at an aloe extract called aloe emodin. One showed that it could block the growth of some head and neck cancer cells in test tubes. A recent study in 2018 showed that aloe emodin might slow down the growth of glioblastoma cells. Glioblastoma is a type of brain cancer. We need more research.
