Evaluation of cell viability and nitric oxide release after treatment of human hepatocellular carcinoma cells with a homeopathic compound of Graviola (Anonna muricata) and Purple Ipe (Handroanthus impetiginosus)
Main Article Content
Abstract
Homeopathy has become increasingly known and used in various treatments, showing excellent clinical results. One of its most common indications is to help treat chronic diseases, directly improving patients' quality of life, especially those with cancer. Hepatocellular carcinoma is a disease that depends on different factors for its development and the success of its treatment. In this context, searching for new therapeutic tools is essential, and homeopathy seems promising. Therefore, Anonna muricata (soursop/graviola) and Handroanthus impetiginosus (purple ipe) have been studied due to their action potential against tumor cells. This study aimed to evaluate the effect of these medicines combined in 1.1mL ampoules, in homeopathic dilutions, on HepG2 (hepatocellular carcinoma) cells through in vitro tests. Cells were cultivated in 75 cm² culture bottles in an oven with controlled temperature and CO2 quantity (37 ºC, 5% CO2). Then, cells were plated in 96-well plates where treatment was performed using the products at different concentrations. After 48 hours of treatment, cell viability analyses were performed by MTT and quantification of the nitric oxide released using the Griess reaction. Treatment with the Anonna muricata D5 (1x10-5) + Handroanthus impetiginosus D5 (1x10-5) formulation resulted in decreased cell viability and increased nitric oxide production by these cells. These findings indicate that this medicine showed an antitumor effect and can be an ally in treating this type of pathology.
