Aloe Vera. While topical use of aloe may not affect your pregnancy, taking it orally may place your baby in danger. Consult your physician prior to using any oral supplement containing aloe.
Probably OK.. Most of the aloe vera plant is edible--the leaves are juicy/succulent. The leaves are thick and contain quite a bit of juice (clear gel) which is often used in making juice or to make skin lotion etc.. It has been used for centuries both internally and external and has not been found to have any significant toxicity. So, at 9 month, i think should be safe. Congrats on the pregnancy. Good luck.
