Introduction

Another alkaloid from V. vir.

Provings

1. Several trials were made by administering it to persons in health, gr. 1/40 dissolved in alcohol being administered ever 1/4 hours until gr. 1/8 had been taken. In 1/2 hours after taking last portion pulse in each case was reduced 8 – 12 beats in m. No nausea or other effects were experienced, and the benumbing sensation of aconite was wanting. (BULLOCK, lac. cit.)

2. Dr. WOOD, pulse 85 sitting, took at 11:40 a. m. gr. 1/18 of sulphate in aqueous solution. 12, no reduction of pulse, but every since taking dose there has been persistent, peculiar numbness in fauces. Took gr. 1/18 more. 12:15, fauces same; general feeling of languor and quietness; sense of exertion on going upstairs. 12:35, pulse unchanged; repeated dose. 1, pulse when quiet 76; fauces same. Took a hearty meal. 1:40, pulse 76 still; another dose. 2:10, pulse 80 took gr. 1/9. 2:40, pulse 74; numbness of throat not noticeable. 3:15, pulse 69; another 1/9 gr. 3:40, pulse 66. 4, pulse 72; took gr. 1/6. 4:30, pulse 73; another 1/6 gr. 5:15, pulse 67; decided feeling of weakness; no other symptoms. 5:30, pulse 68; any exertion an effort, and when forced sending pulse rapidly up to 110 (walking once or twice round room sufficient to do this). 6, pulse 70; any exertion painful. A friend coming in asked what was the matter, he looked so painful. A friend coming in asked what was the matter, he looked so languid. 6:15, pulse nearly 70, down at times to 62. At 6:20 took supper, with 2 oz of brandy, but pulse continued 66-70. No digestive disturbance of other symptom has been manifested since taking the drug, save only the slowing of the pulse and the not unpleasant muscular languor. The benumbing of the throat seemed local, and there was no tingling sensation as from aconite. (Amer. Journ. of Medorrhinum Sc., 1870, i, 53.).

Experiments an animals

The results obtained by my investigations as to the physiological action of Viridia may be summed up as follows: a. It appears to be very slightly, if at all, locally irritant. b. It has no action at all upon the alimentary canal, never producing either vomiting or purging. c. It exerts no direct influence on the brain, and the pupil is unaffected by it, except it be an indirect dilatation just before death. d. It is a spinal motor depressant (probably directly so), producing death by paralysis of the respiratory nerve- centres, and is without action on the muscles or nerves. e. It is a direct depressant to the circulation, lowering the force and rapidity of the blood-stream, slowing the action of the heart, and finally affecting the force of the single beat, independent of any spinal action it may exert. ( Ibid., p. 50.).

Richard Hughes
Dr. Richard Hughes (1836-1902) was born in London, England. He received the title of M.R.C.S. (Eng.), in 1857 and L.R.C.P. (Edin.) in 1860. The title of M.D. was conferred upon him by the American College a few years later.

Hughes was a great writer and a scholar. He actively cooperated with Dr. T.F. Allen to compile his 'Encyclopedia' and rendered immeasurable aid to Dr. Dudgeon in translating Hahnemann's 'Materia Medica Pura' into English. In 1889 he was appointed an Editor of the 'British Homoeopathic Journal' and continued in that capacity until his demise. In 1876, Dr. Hughes was appointed as the Permanent Secretary of the Organization of the International Congress of Homoeopathy Physicians in Philadelphia. He also presided over the International Congress in London.
