A note about Comfrey:
Although this herb is known for its medicinal values and curing abilities, there are a few side effects if taken inappropriately or improperly. There have been many studies proving its safety.
But, in one study conducted with rats, a large quantity of comfrey caused pre-cancerous liver cells when injected directly into their bloodstream .
Pregnant and breastfeeding women should use caution when using any kind of Comfrey application. Keep all medicines, creams and ointments away from children. Store them at the right temperature and preserve them in an airtight container.
