Namrita Lall is a botanist and pharmacologist of Indian–South African descent, holding a professorship in plant sciences at the University of Pretoria. She occupies the South African Research Chair dedicated to Plant Health Products based on Indigenous Knowledge Systems and spearheads investigations in bioprospecting, with particular attention to cosmeceuticals and therapies targeting tuberculosis and cancer.

Background

Originating from India, Lall earned both her BSc and MSc degrees in botany at the University of Transkei. Her master's research on Impatiens flanaganiae was recognized with a Southern Africa Association for the Advancement of Science Medal in 1996.

In 1997, she became affiliated with the University of Pretoria to pursue doctoral studies under the guidance of medicinal plant specialist Marion Meyer. Her PhD research uncovered naphthoquinone derivatives as promising candidates for addressing liver complications associated with tuberculosis treatment. After completing her doctorate in 2001, she continued at Pretoria, advancing from lecturer to professor.

As holder of the South African Research Chair, Lall promotes innovation in developing plant health products rooted in indigenous knowledge, fostering both research initiatives and postgraduate training. She established the African Phytomedicine Scientific Society in 2023 and currently serves as president of the International Society for Ethnopharmacology.

Research

An NRF-rated scholar, Lall has edited four volumes focused on medicinal plants. According to Essential Science Indicators, she ranks within the top 1% globally in pharmacology and toxicology based on citation metrics. She is credited with multiple patents related to medicinal plant discoveries: four granted in South Africa, three in the United States, alongside several others across the European Union and East Asia. At the University of Pretoria, she leads a team within the Medicinal Plants Sciences Programme concentrating on South African flora for combating tuberculosis, cancer, dermatological conditions, as well as exploring their antibacterial, hepatoprotective, and immunomodulatory properties. Her research emphasizes isolating and purifying bioactive plant compounds to improve healthcare accessibility worldwide, working closely with industry leaders specializing in botanical products. Additionally, she has contributed to innovations addressing periodontal diseases.

Her laboratory prioritizes bioprospecting and drug development through validating traditional ethnopharmacological knowledge, aiming to commercialize active constituents for pharmaceutical and cosmeceuticals markets. By 2023, her group had formulated 19 prototype botanical extracts undergoing comprehensive R&D; eleven of these have secured patents domestically or internationally. One extract targeting hyperpigmentation has been commercialized internationally, while a liver-supportive complementary medicine branded as Limunone is available within South Africa. Lall also coordinated the DSI Cosmeceutical Consortium, which focuses on leveraging indigenous biological resources for cosmetic product innovation.

Other honours

In March 2002, Lall was awarded the UNESCO-L'Oréal International Fellowship to advance her bacteriology research.

The Department of Science and Technology of South Africa recognized her contributions to indigenous knowledge systems with the Distinguished Women in Science Award in August 2011.

In April 2014, President Jacob Zuma conferred upon her the Order of Mapungubwe in Bronze in acknowledgment of her exceptional medical science achievements, particularly her research on antimycobacterial compounds for tuberculosis treatment.

Most recently, in October 2021, University of Pretoria Vice-Chancellor Tawana Kupe honoured Lall with the Vice-Chancellor's Award for Excellent Supervision, celebrating her outstanding guidance of postgraduate researchers.
