Botanic Gardens Conservation International

[2] Dedicated to plant conservation and environmental education, the charity works to support and promote the activities of its member gardens.

Its official stated mission is to "mobilise botanic gardens and engage partners in securing plant diversity for the well-being of people and the planet."

These included yew trees (the bark is used for cancer drugs, paclitaxel); Hoodia gordonii (from Namibia, source of weight loss drugs); half of Magnolias (used as Chinese medicine for 5,000 years to fight cancer, dementia and heart disease); and Autumn crocus (for gout).

The group also found that 5 billion people benefit from traditional plant-based medicine for health care.
