Is Aloe Vera dangerous?
It can be - especially if you use the wrong variety or if you try injecting it (some people have died through the injection method). Make sure you are using Aloe Barbadensis Miller - most commercial products are made from this.
Avoid the outer skin or using the 'Whole Leaf'. The rind is highly toxic and is the plants natural defence against being eaten in the wild!
Do not drink large amounts of Aloe straight away. It cleans the digestive tract and so may have a laxative effect is large quantities until your body is used to it.
Do not drink/use Aloe if you are pregnant and you have never drunk Aloe before. See Who can use Aloe Vera
