Can you apply Wanjin oil during pregnancy?

Patient's question:

No

Doctor's answer:

The ingredients of cooling oil include camphor, peppermint oil, eucalyptus oil, and cinnamon, etc. For pregnant women, camphor can also cross the placental barrier and affect the normal development of the fetus, potentially leading to malformations, stillbirths, or miscarriage. The harm is particularly greater during the first three months of pregnancy.
