Effects on parasitic diseases

An early report shows that cholera epidemics in Europe were effectively tackled by homeopathic medicines (Leary, 1994). The work refers to the epidemic in 1854. The results may not be reliable because modem diagnostic techniques were not available at that time and adequate placebo controls were not kept. Abrotanum D1 was tested on 27 dogs and 26 cats infected with intestinal nematodes in a Veterinary clinic of Germany and the results were positive (Krause, 1993). 

Hypericum 200 produced a decrease in firing rate in case of 5 neurons and the effect lasted from 1.5 - 14 min with a latency of 1 sec to 2 min. In two neurons there was a transient potentiation followed by inhibition. In one neuron there was an increase in firing rate within 2 min and the effect lasted for 11 min. Arsenic 30 produced a marked increase in firing rate within 1 sec and the effect lasted for 20 sec. In all the cases the control did not show any marked change in the firing rate (Sukul et al., 1991). 

In the above experiments we see that the action of a homeopathic potency starts within a few seconds to a few minutes. The same drug may produce both inhibitory 

In another experiment we examined the response of hypothalamic neurons of rats to potentized Nux vomica. Rats used in the electrophysiological tests all belong to Charles Foster (CF) strain. A batch of 15 rats was given 20% ethanol by force drinking at 1.5 ml/kg body weight for 7 days. They were given food and water ad lib. After 7 days neuronal activity in the lateral hypothalamic area (LHA) of these
