I am a nurse by profession and the best sources are as follows:
Scribd - they provide you with detailed cases.
nurseslabs- if you want to know more about health issues and how they are being treated you can check it out here.
WebMD- is a popular site with health care professionals and with regular individuals. It is very informative.
MedicineNet, Drugs.com - if you want to learn more about your given medications.
Being Exposed to Radiation. Also, being exposed to harmful Toxins.
D providing more cost effective alternatives to prescribed drugs
Folic acid is good for pregnancy. I think all woman should take it during pregnancy. It helps prevent birth defects.
Hope this helps.
