CCNOW is one payment gateway/processor which accepts herbal or alternative medicine sites. Ayurvedaforall.com, arguably the largest ayurvedic shopping portal, was struggling to find a payment processor other than paypal and we zeroed in CCNOW as the possible solution. However OSCommerce(the shopping cart used by Ayurvedaforall) didn’t have an available addon for CCNOW. We developed a addin from scratch and implemented in successfully. If you are looking to integrate CCNOW with OSCommerce please get in touch.
