Aloe barbadensis (Miller), Aloe vera, has a long history of use as a
topical and oral therapeutic. The plant is the source of two products,
gel and latex, which are obtained from its fleshy leaves. Aloe vera
products contain multiple constituents with potential biological and
toxicological activities, yet the active components elude definition.
Ingestion of Aloe vera is associated with diarrhea, electrolyte
imbalance, kidney dysfunction, and conventional drug interactions;
episodes of contact dermatitis, erythema, and phototoxicity have been
reported from topical applications. This review examines the botany,
physical and chemical properties, and biological activities of the Aloe
vera plant.

It sounds yummy.

I wouldn't hesitate, I'd forget it immediately.

I'd be much more concerned with soy and tofu and fluorides in water,
tea and potatoes, if you are concerned with thyroid issues.
