HP Ingredients was founded in 2001 by Annie Eng, who is a pioneer in the botanical ingredient supply chain.


Did you know that HP stands for Herbal Powers? While growing up in Malaysia, Annie knew that herbs were very powerful for human health and wellness. So she formulated her company and today we are thriving.


We are enjoying longevity because of Annie’s vision and commitment to research first and foremost. She has forged lasting relationships with researchers worldwide who are interested in exploring the phyto-physiological properties of herbs.


Please look at the names of some of our published papers for an idea as to the depth and reach of our research on two of our most popular ingredients — Bergamonte® and ParActin®.
