The beans are harvested as whole dried seeds and are noted for their high natural physostigmine content, the alkaloid used in pharmaceutical research. SPEARSON LIMITED lists the beans as an organic‑tier offering, stored at its facility on Senkyere House, Block A, Airport Roundabout. The product falls under pharmaceutical and hazardous‑material regulations, requiring appropriate licences for cross‑border movement.
In the trade, wild‑harvested Calabar beans normally contain 0.5‑1.0 % physostigmine by weight, a range considered typical for the species. Dried beans are usually shipped with moisture levels between 8 % and 12 %, which helps preserve alkaloid stability. Standard bulk packaging employs 25 kg jute bags, a common format for dry seed commodities. The beans are classified as Category 1 toxic seeds, meaning they must be handled according to hazardous‑material guidelines.
Primary buyers include pharmaceutical manufacturers, research laboratories and specialised herbal product firms that require a reliable source of physostigmine. SPEARSON LIMITED offers flexible minimum order quantities and can ship under FOB or CIF terms, with payment accepted via L/C or T/T. Prospective importers should confirm the exact shipping port, lead‑time expectations and any additional documentation such as MSDS before finalising the contract.

Calabar bean (Physostigma venenosum) is a highly toxic leguminous seed native to West Africa, historically known as the eserine or ordeal bean. It serves as a primary source of physostigmine (eserine), a key alkaloid in pharmaceutical research and limited ophthalmic applications. Due to its potent alkaloid profile, international trade is regulated under pharmaceutical and hazardous material frameworks, requiring proper licensing and documentation for import and export.

Before placing an order, buyers should verify that SPEARSON LIMITED holds the necessary export licences for toxic botanical material and can provide a current Material Safety Data Sheet. Request a laboratory certificate confirming the physostigmine percentage and moisture content of the specific batch. Because the supplier’s response rate is recorded as zero, establishing a direct communication channel and obtaining written confirmations is essential to reduce regulatory risk.
The typical shipping arrangement uses FOB or CIF incoterms, allowing the buyer to choose between port‑side delivery or freight‑included service. Lead‑time estimates are not disclosed in the listing, so the importer should ask the supplier for an expected dispatch window based on current harvest cycles. Payment can be made by irrevocable Letter of Credit or Telegraphic Transfer, and the buyer should confirm the bank details and any required advance deposits before shipment.
Upon arrival, the consignment should be inspected for packaging integrity and moisture level to ensure the beans have not absorbed excess humidity. An independent laboratory test for physostigmine concentration and foreign‑matter content can verify compliance with pharmaceutical standards. The supplier is expected to furnish the original MSDS, phytochemical analysis report and any certificate of origin required by the importing country’s customs authority.
