King’s Dispensatory: “Lycopus fills an important place in Eclectic therapeutics. Its action is chiefly exhibited on the vascular structures and the sympathetic nervous system. It is a certain sedative, mildnarcotic, subastringent and tonic. Its sedative action is most pronounced and most frequently indicated where
the vascular action is tumultuous, the velocity of the pulse rapid, with evident want of cardiac power. It is for this purpose that it is principally employed in advanced stages of acute disease with great debility, and in chronic disease with frequent pulse. It improves the circulation and its good influence is extended to all the parts under the control of the vegetative system of nerves. As a sedative, Prof. Scudder classes it with aconite and veratrum.
It acts somewhat like digitalis inreducing the velocity of the pulse, but is devoid of the dangerous effects resulting from the use of that drug, and hence has proved useful in some cardiac affection. It controls excessive vascular excitement, general irritability and diminishes exalted organic action. Upon the stomach its action is kindly, improving the appetite and serving as a mild gastric tonic. Normal secretion is established by it and blood-making
and nutrition are improve.

Ellingwood describes its Specific Symptomology thus – “In diseases ofthe heart, either functional or organic, marked by irritability and irregularity of the organ, dyspnoea, feeling of oppression in the cardiac region, its administration is followed by gratifying results. Hypertrophy and dilatation have been known to undergo marked diminution in consequence of its administration. ” Therapeutic uses – “It possesses
tonic, sedative, astringent and narcotic properties and has been successfully used in incipient phthisis, haemoptysis, etc. It act like digitalis in reducing the velocity of the pulse, but has no cumulative effects. In pericarditis and endocarditis its sedativeaction lessens the frequency of the pulse, irritability and its attendant inflammation, in a manner equaled by no other remedy. Exopthalmic goitre. In diseases of the respiratory apparatus lycopus has
been found to be very useful. Haemoptysis, associated with rapid and tumultuous heart’s action, yields readily to its influence, as does hemorrhage from any part. Hale lauds lycopus highly for its efficiency when used in cases of incipient phthisis and in chronic inflammatory diseases of the lungs. by regulating the heart’s action and equalizing the circulation in the lungs it mitigates or arrests the local inflammation.
