Rhus Venenata.

Rhus Venenata.

Rhus venenata. Poison Elder. Poison Sumach. Swamp Sumach.-It is frequently named “R. Vernix,” and it is given under this name in Hempel’s Jahr., but the name belongs properly to the allied Varnish-tree of Japan. (North America, in swampy ground.) N. O. Anacardiaceae. Tincture of fresh leaves and stem.

Characteristics.-Rhus ven. is one of the most actively poisonous of the Rhoes. P. B. Hoyt, who (according to Hale) first drew attention to it, and made the first provings, says it is more poisonous than Rh. t., which he can handle with impunity, whilst he was violently affected by Rh. v. in spite of extreme caution. Further, he considers it more actively curative; in a case of Rhus sore throat, when Rh. t. failed Rh. v. acted with excellent effect. Another observer, Butman, says that persons who have been poisoned by Rh. t. are more liable than others to Rh. v. poisoning, the Rh. v. is “set to work” by the Rh. t. On the other hand Rh. v. in the attenuations is credited with the cure of Rh. t. poisoning. Hoyt’s experience is interesting. Wishing to prepare a tincture he went to a swamp and procured some sprouts. In doing this he had on a pair of buckskin gloves, and kept carefully to the windward side of the plant. Nevertheless in an hour and a half a most intense itching and burning (more burning) set in in scrotum and penis. The glans was very painful; slight friction > for a moment the itching but not the burning. The symptoms continued next day. At 11 a.m. he made the tincture, using great caution in manipulating the plant. At 3 p.m. itching and burning began on back of right hand. A restless night followed. Awoke in morning with itching, especially on palmar surface of wrists. This spread all over body, symptoms steadily advancing. Dizziness; eyes and ears became affected, fever set in. When the symptoms passed off it was found that some chronic dyspeptic symptoms and inflammation of the eyes had been much benefited.-I have frequently used Rh. v. with good effect in skin diseases. Bayes told me of a case of universal eczema with intense distress in an old man which he cured in a fortnight with Rh. v. A case of pemphigus in a young man of 27 came under my care after years of treatment under allopathic specialists who had given him Arsenic until they could give no more, telling him at the same time that nothing but Arsenic could do him any good. Rh. v. 3x and 30 completely cured in a few months, and the cure enabled the patient to marry. I have found Rhus an excellent remedy for arsenical overdosing. A minor use of Rh. v. is as a topical remedy in itching, burning chilblains. The Ø tincture painted on relieves almost instantly and practically cures the chilblains in a large number of cases. Rh. v. has many symptoms referring to the bones; and according to Hering it affects those parts where the bones are directly covered with skin, as the forehead, backs of lingers, &c. There is a “pain half way down the oesophagus” which is probably a variant of the Rhus “Pain between the shoulders on swallowing food.” Peculiar Sensations of Rh. v. are: Sensation as if mouth and throat had been scalded. As if sand on lips; in mouth. Sensation in arm as if the bone would break. Pains wander about; upward and downward along the periosteum; come and go suddenly; chill runs up back. Butman observed that blondes are more susceptible to Rh. v. poisoning than brunettes. When once affected persons are liable to a renewal of the affection (without further poisoning) each year at the same time. Persons poisoned by Rh. t. and r. are more liable to be poisoned by Rh. v. Children are more readily poisoned than adults. Hale records a case bearing on the comparative action of Rh. v. with Rh. r. and Rh. t.: A lady had several times every year a sore mouth, with intense redness of mucous membrane of tongue, cheeks, and fauces in small vesicular points; intense burning and feeling as if mouth and throat had been scalded. If unchecked every mucous membrane including those of rectum and vagina became involved. No remedy helped till Rhus was tried. Rh. r. and Rh. t. only slightly relieved, but Rh. v. 3 always removed the affection quickly. Under the name Rhus vernix E. F. Beckwith relates (M. A., xx. 369) the poisoning of Mrs. T. Williams, 32, sandy hair, light complexion, good general health. Twelve years before she had worked all day over a stove in which the wood of Swamp Sumach was burned. She was badly poisoned, was unable to see for four or five days, and was treated with lotions of sugar of lead and butter-milk. Ever since then she had a rash just before the menses, or if she took cold. At the time Beckwith saw her she had a lump in centre of left breast, a dense mass occupying nearly one-half the gland substance, which she believed to be cancer, a sister having died of what was said to be cancer of the breast. She had first noticed it, the size of a hazel-nut, six years before when nursing her last child. The symptoms connected with this were also < before menses and had Rhus characteristics. The symptoms from this patient I have marked (B) in the Schema. The symptoms were < by touch and pressure. > Gently rubbing and scratching. < Before stools. < Damp days. < Hot weather. < Rest. > Moderate exercise or open air. > Hot bath. Chills in warm room. Washing with cold water or snow > itching on back. < Mental exercise. Motion < pain in elbow. Walking < frontal headache. Eating raw things < burning of lips. All symptoms < morning after waking. Diarrhoea 4 a.m. “Pain as if sprained” shows the relation of this Rhus to sprains. It is most poisonous on hot days in summer; to persons immediately after a meal; and to those in a state of perspiration-“if my skin was perfectly dry when collecting the juice of Rh. v., it had not the slightest effect on me” (Bigelow, quoted by Hale).


Relations.-Antidoted by: Pho., Bry. Clem. (itching on hands and genitals, anus, lips, mouth, and nose) Ranunc. (rheumatic pains < on taking cold); Nit. ac. (sprained pain in r. hip).
