Studies have shownthat homeopathy modulates the activity of both single-and multi-celled organisms;therefore, we propose a study into the action of Arnica Montanaand S. cerevisiae fungus nosode on growth "in vitro", and on the fermentation of S. cerevisiaeon brewer's wort.


250 µL of medication in 30% alcohol were placed in 5 mL of Sabouraud Broth (SB) or wort, with 20 µL of fungus ata McFarland standard of 0.5 and in a dilution of 1100. Fungal growth was evaluated via spectrophotometry at 600 nm or a cell count in a Neubauer chamber in a kinetic of 1 to 5 days' incubation at 25ºC. The production of alcohol by the fungus was evaluated using the BRIX index in the samekinetic. 1x107fungi/mL were previously incubated with medication for 5 days and, afterwards, placed in 20 mL of fresh wort, incubated at 25ºC for 7 days and evaluated for growth and sugar consumption. Resultsand


The SB results revealed that after 2days incubation with Arnica30CH, an increase in fungal growth was observed (p<0.0001), whilewith nosode 6 and 30CH there was a reduction in growth after 2 and 5 days incubation (p<0.001). The fungi incubated with Arnica30CH exhibited increased sugar consumption after 2 and5 days incubation (p<0.05), while the nosode 30CH resulted in lower sugar consumption after 2 and 3 days incubation (p<0.05). The results for fungal growth and sugar consumption with the wort were similar to those using SB.The fungalcultures previously incubated with homeopathic medication and subsequent incubation with fresh wortindicated a loss of distinction, bothin terms of fungal growth and sugar consumption. This piece of data may suggest action by the homeopathic medication only when in contact with the cells.


The treatment of the S. cerevisiae fungus using Arnica and the S. cerevisiae nosode produced a significant modulation in fungal growth and sugar consumption.
