Pregnancy is a super important time. Do not take by inhalation, ingestion or other exposure anything that is a potential toxin for the body. Things to avoid: 1) Caffeine - in low to minimal doses, it is clear that caffeine is safe for pregnant women and their offspring. Caffeine easily crosses into the placenta and thus the baby's circulation. In utero babies cannot metabolize caffeine well putting them at risk with increasing exposure. The data does not support the same reality for more moderate to high doses. Caffeine is known to raise blood pressure and heart rate in all users in variable numbers based on metabolism capabilities...... plus a literature review and a recipe. Enjoy, Dr. M
