USP Announces Proposed New Monographs for Dietary Supplements Cat's Claw and Pygeum

Rockville, Md. -- USP has created new monographs for Cat’s Claw and is publishing revisions made to new Pygeum monographs. All of these new monographs are available for review in USP’s May–June 2004 edition of Pharmacopeial Forum (PF) vol. 30(3).

The newly created monographs are: Cat’s Claw, Powdered Cat’s Claw, Powdered Cat’s Claw Extract, Cat’s Claw Capsules, Cat’s Claw Tablets, Pygeum, Pygeum Extract and Pygeum Capsules.

Cat’s Claw is grown in the rain forests of South America and is marketed as a dietary supplement with a structure/function claim related to strengthening the immune system and for joint health. Pygeum, produced from an evergreen plant found in Africa, is marketed as a dietary supplement for prostate health. *

The Cat Claw’s monographs are found in the Pharmacopeial Previews section, and the Pygeum monographs appear in the In-Process Revision sections of the PF. Publication of these announcements in PF is an opportunity for the public to provide comments before the monographs are finalized.

The PF is USP’s journal of standards development and the primary vehicle for the public to provide input or comments on USP standards.

Comments on the monographs should be addressed and mailed to Dr. Gabriel Giancaspro at USP, 12601 Twinbrook Parkway, Rockville, MD 20852. Additional questions concerning dietary supplement monographs can be sent to [email protected].

* Recognition in the USP–NF is for purposes of standardization only. It does not mean the effectiveness of the articles have been evaluated by USP.
