Many members are recognized for their valuable roles in maintaining soil health. Specifically, they contribute to soil fertility by acting as effective nitrogen fixers. This natural process enriches the ground, which in turn allows these species to be cultivated or thrive ecologically, distinguishing their value from their medicinal counterparts.
