Abstract
BackgroundCancer is one of the leading causes of morbidity and mortality. Current treatments include chemotherapy, radiotherapy, etc., are known to be associated with several side effects. Hence, complementary and alternative medicine is growing in acceptance around the world, particularly Ayurvedic formulations. MAK is one of the most scientifically acclaimed formulations with potential anti-neoplastic and chemoprotective properties. ObjectiveTo study literature available on the anti-neoplastic and chemoprotective effects of MAK. Material and methodsA systematic literature review was conducted using multiple web-based sources: Google Scholar (185), PubMed (33), DHARA (49), AYUSH research portal (2), EBSCO (66), and CTRI (1) for all studies published before February 2021 using keywords: Maharishi Amrit Kalash, Amrit Kalash, Amrit, MAK-4, MAK-5, MAK-7, and others. A manual search was conducted on the reference list of all included articles to identify additional studies. Studies with cancer and/or chemotoxicity outcomes were selected manually. Evidence from both preclinical and clinical level studies have been included in the current review. ResultsOut of total 79 studies on applications of MAK, 13 studies were found to state its anti-neoplastic and chemoprotective effects. The studies showed role of MAK in initiation of neoplastic transformation of cancer cells (1), carcinogenesis inhibition (4), metastases inhibition/reduction (1), cancer growth inhibition (4), induction of morphological and biochemical differentiation of cancer cells (3), and reduction in chemotoxicity (4). In studies with controlled clinical trial design (3), MAK use among patients with cancer showed a significant reduction in anorexia, vomiting, and other side effects associated with chemotherapy. A general improvement in quality-of-life scores (Karnofsky Performance Status) and well-being was also observed among patients using MAK. ConclusionEvidence from pre-clinical studies show promising results for use of MAK as an anti-cancer and a chemoprotective agent. More clinical studies are needed to assess the impact of MAK use for tumour regression among patients with cancer. Current scoping review provides sufficient evidence on MAK to be considered for further exploration for its anti-cancer/chemoprotective effects in bigger randomized clinical trials.
