Drug Discovery from Natural Products

Screening of various plants both terrestrial (medicinal &ornamental) and marine (seaweeds & seagrasses) for different pathological conditions such as inflammation, cancer, diabetes, ulcers and dyslipidemia, leading to isolation of lead bioactive molecules followed by studying the mode of its action using biochemical and molecular techniques in drug discovery and development.

Standardisation and Scientific Validation of Indian System of Medicine Drugs 

Bringing our ancient traditional knowledge to the global limelight by validation of drugs of ISM is highly warranted. Based on a multidisciplinary approach some Ayurveda/Siddha drugs of herbal and herbomineral origin are being scientifically evaluated, validated and documented for diseases such as diabetes, arthritis and ulcers.
