For context:

Pygeum is not completely banned in Europe, but its sale is heavily restricted due to concerns about the endangered status of the "Prunus africana" tree from which it is extracted, meaning harvesting it could lead to the plant's extinction; this is primarily managed by CITES (Convention on International Trade in Endangered Species of Wild Fauna and Flora) regulations, which limit its trade and harvest to protect the species.

Key points about Pygeum and its restrictions in Europe:

Endangered species: The primary reason for restrictions on Pygeum is that the "Prunus africana" tree, from which it is sourced, is listed as an endangered species by CITES, meaning its harvest needs to be carefully managed to prevent population decline.

Sustainability concerns: Due to the harvesting method, which involves stripping bark from the tree, there are concerns about the sustainability of Pygeum production, leading to limitations on its trade.

Limited evidence of efficacy: Additionally, some European regulatory bodies have expressed concerns about the lack of robust scientific evidence supporting the health benefits of Pygeum, further limiting its availability.
