Rehmannia

Rehmannia is very nourishing to the kidneys and blood, and rejuvenating at deep levels. It is considered an excellent antiaging herb, and supports the Jing directly in the kidneys, bringing better sexual function and reproductive health, along with increased fertility. It is considered calming and grounding to excess Yang, helping keep that fiery energy balanced and contained.

Recent research also indicates that Rehmannia scavenges and counteracts the free radicals associated with some types of hearing loss and tinnitus, protecting the hearing. Like other Jing herbs, Rehmannia is also strengthening to the lower back.
