Dear Stockholders:

We are pleased to inform you that Pure World, Inc. (the "Company") has entered
into an Agreement and Plan of Merger dated as of June 6, 2005 (the "Merger
Agreement"), with Nanturex S.A. ("Parent") and Naturex Acquisition Corp.
("Purchaser"), a newly formed corporation and wholly owned direct subsidiary of
Parent. Pursuant to the Merger Agreement, Purchaser has commenced an offer to
acquire each issued and outstanding share of Common Stock, $0.01 par value, of
the Company (the "Shares") for $4.30 per Share in cash. If the tender offer is
completed, Purchaser will thereafter be merged into the Company, with the
Company surviving the merger as a subsidiary of Parent. All of our then
outstanding Shares (other than Shares held in the treasury of the Company, held
by Parent, Purchaser or any of their subsidiaries or held by stockholders who
properly exercise appraisal rights under Delaware law) will be cancelled and
converted into the right to receive $4.30 per share in cash. The tender offer is
conditioned on, among other things, there being validly tendered and not
withdrawn before the expiration of the tender offer a majority of the Shares on
a fully diluted basis.

The Board of Directors of the Company, by unanimous vote (except for the
abstention of Paul O. Koether, the Chairman of the Board of Directors and the
Company's principal stockholder): (a) has determined that the Merger Agreement
and the related transactions, including the tender offer and the proposed
merger, are fair to, and in the best interests of, the Company and our
stockholders; (b) has approved the Merger Agreement, the tender offer and the
proposed merger; and (c) recommends that our stockholders accept the tender
offer and tender their Shares in the tender offer and, if required, approved and
adopt the Merger Agreement.

Enclosed are Purchaser's Offer to Purchase, dated June 17, 2005, and the related
Letter of Transmittal, which our stockholders can use to tender their Shares in
the tender offer. The attached Schedule 14D-9 describes in more detail the
factors considered by our Board in reaching its conclusions and making its
recommendation, and contains other information relating to the tender offer. We
urge you to consider this information carefully.

                                Sincerely,


                                /s/ Qun Yi Zheng, Ph.D.
