Abstract
Homeopathy has been increasingly standing out for its proven clinical benefits and for providing a course of treatment with fewer side effects to patients, thus promoting a better quality of life for them. Homeopathic therapy can be used in different contexts and is an additional alternative for treating cancer patients in Integrative Medicine. Within this context, hepatocellular carcinoma has a high mortality rate and, in most cases, is diagnosed in advanced cases. Therefore, this study evaluated the in vitro efficacy of the association of the homeopathic medicines Taraxacum officinale and Lycopodium clavatum against HepG2 cells. For this purpose, cells were grown in 75 cm² flasks and then plated in 96-well plates. The treatment with Taraxacum D4 + Taraxacum D8 + Taraxacum D12 and Taraxacum D5 + Lycopodium D6 at concentrations of 20, 40, and 60 µL/mL was added to each well. After 48 hours of incubation in an oven at 37ºC, 5% CO2, cells were subjected to the cell viability test by MTT. A decrease in viability was observed compared to the control group (cells without treatment). In addition, the medicine Taraxacum officinale was more effective in decreasing cell viability than the other medicines in the three conditions tested. In conclusion, the homeopathic medicine Taraxacum D4 + Taraxacum D8 + Taraxacum D12, in accord of potencies, is promising against hepatocellular carcinoma cells and can be used to aid in the treatment of this type of cancer.
