Sida cordifolia is a shrub native to India that now grows worldwide. It's a common ingredient in herbal preparations in many systems of traditional medicine.
Sida cordifolia contains ephedrine, which is an amphetamine-like stimulant.
Despite serious safety concerns, people use Sida cordifolia for asthma, allergies, fatigue, erectile dysfunction, common cold, and many other conditions, but there is no good scientific evidence to support these uses.
Sida cordifolia contains ephedrine, which is an amphetamine-like stimulant that can cause harmful side effects. Since April 2004, the US FDA has banned the sale of ephedra, Sida cordifolia, and other products that contain ephedrine. Don't confuse Side cordifolia with Chinese Mallow, Mallow, or Marshmallow. These are not the same.
