The Centre of Innovation for Complementary Health Product (COI-CHP) was established in 2016 as a strategic partnership with Enterprise Singapore (formerly known as SPRING Singapore) to support Singapore-based Complementary Health Product (CHP) enterprises meet the growing challenges and technological advances. 


With a multi-disciplinary and research-intensive team, this national Centre offers innovative and customised solutions to enterprises in CHP product development that includes product formulation, chemical and biological analysis, as well as safety and efficacy testing.  The three categories of CHP are traditional medicines, health supplements and functional foods.


To support enterprises in the provision of innovative and customised solutions to enhance the safety, efficacy and quality standards of complementary health products.


COI-CHP, Natura Biotechnologies Pte Ltd, and CVS Secured S$249,200 in TPRF 16th Grant Funding


We are pleased to announce that COI-CHP, in collaboration with Natura Biotechnologies Pte Ltd ("Natura") and Centre of Veterinary Science ("CVS") has secured a grant of S$249,200 during the recent Temasek Polytechnic Research Funding (TPRF) Grant 16th Call for the development of a novel anti-dengue herbal product.


The project is led by Dr Li Huan, Principal Investigator (PI), Mr Samin Yasar Ahmad (Co-PI) and Ms Chen Yuan Ting (Team Member), and jointly supported by Dr Jiang Feng Li, Head of CVS, Dr Shirhan, senior scientist of CVS, as well as Dr Alex Liu, Mr Liu Liren and Mr Matthew Koh (all 3 Directors of Natura). 


COI-CHP and Natura are aiming to develop an anti-dengue herbal product through an in-vivo study. The team has completed a TPRF Proof of Concept (POC) project in 2023.  In-vitro data showed promising results of the herbal product in reducing four serotypes of dengue virus titre, as well as exhibiting broad-spectrum anti-inflammatory properties.  The background IP of this proprietary herbal product is co-owned by Temasek Polytechnic and Natura Biotechnologies Pte Ltd.


This collaboration and the secured funding highlight the potential impact of this innovative research on dengue treatment, leveraging the combined expertise of COI-CHP, Natura, and CVS.
