Research articles related to Digitalis purpurea:
Hepato- protective action: The present research was aimed to study the in vivo hepato -protective activity of methanolic extract of Digitali Purpurea L.in CCl4 induced hepato toxicity in albino rats. The extract of Digitalis Purpurea L. and silymarin administration prevented the toxic effect of CCl4 on the above serum parameters in both preventive and curative models. The present study concludes that, methanolic extract of Digitalis Purpurea Lhas significant hepato protective activity against CCl4induced hepatotoxicity,
Cardiac protection: Digitalis is of great value in chronic valvular cardiac disease, with failing or broken compensation, but it must be used with judgment, observing the need in the weak, fast, and irregular pulse, deficient urination, and dropsy. When hypertrophy of the heart overbalances dilatation, and evidences of arterial hyperaemia are present, digitalis is likely to aggravate the condition, or otherwise do harm.
