 M. Teste says that the pathogenesis of Lachesis presents many symptoms similar to Belladonna, but with some difference in the chronological order of their manifestations, and with a persistent character, which might lead to the supposition that Lachesis corresponds to the chronic diseases of which Belladonna offers us, in a certain degree, the acute form.
