15. Greater Burdock (Arctium lappa)
- Medicinal Use: Joint Pain, Fevers, High Blood Pressure, Bladder Infections
The Greater Burdock Plant tends to do most of what people claim it can do. At least, as long as it is used correctly. Several Eurasian and even the Chinese used this medicinal plant to help with symptoms from colds and other viruses.

It has proven to be useful in increasing the flow of urine, helping with bladder infections, and assisting with complications of syphilis. Due to being capable of killing several germs, it can even help with some fevers and joint pain. It acts somewhat like an NSAID, which is likely why people find it can also help with blood pressure issues and treat acne.
