Signs
Drosera rotundifolia. Round-leaved Sundew. Common Sundew.
N.O. Droseraceae.
CLASSIFICATION The Droseraceae, or Sundew family, is a family of insectivorous plants comprising some 105 species in 4 genera: Drosera, Drosophyllum, Aldrovanda, and Dionaea [Venus' flytrap]. Drosera is the largest genus; it is cosmopolitan, with concentrations in Australia, New Zealand, and South Africa. The family commonly is to be found in acid bogs and other waterlogged soils; the genus Aldrovanda is aquatic and rootless.
FEATURES The leaves of Drosera and Drosophyllum are covered with long, reddish glandular hair which are tipped with a small drop of a sticky fluid. In the genus Drosera these hairs are motile and entrap and digest insects by secreting proteolytic enzymes and ribonucleases. This process is usually aided by bacterial activity. Different species of Drosera have different way of entrapping insects. In some, such as D. rotundifolia, the whole leaf can fold in to eventually cover the trapped insect; other Drosera species move only the tentacles to cover the insect. These motions are slow, taking minutes or hours to occur. Drosera rotundifolia requires a cold dormancy period.
NAME The name Drosera comes from Gr. droseros, dewy. This alludes to the appearance of the glandular leaves, on which the small drops of sticky fluid glisten like dew drops in the sun. The secretion becomes most abundant when the sun is at its highest. The specific name 'rotundifolia' means 'round-leaved.'
FEATURES Drosera rotundifolia is native to Europe and North America. It compensates for the low available nutrients [nitrogen, phosphor, calcium] in its habitat by catching and digesting insects, absorbing these nutrients through its leaves. Insect capture enhances its growth and reproduction. Its shallow roots consist of a taproot, which is functional for less than a year and then replaced by mostly horizontal adventitious roots. The long-stalked, round leaves form a basal rosette and have on their upper surface long red viscid hairs. The flowers are very small, white, arranged on one side of the scape, and when young are coiled inwards. The sepals are five in number, as are also the petals and stamens. In their organs of fructification sundews are closely allied to the violets. The fruit is a capsule with numerous small seeds. Fruits often persist unopened, and seeds are released when the fruit rots. Capable of floating for days on water surfaces, seeds may be carried some distance with snowmelt and flooding. Drosera occurs most often in bogs, but also in swamps, rotting logs, mossy crevices in rocks, or damp sand along streams. It prefers sites with a high water table or high precipitation and humidity. Flooding can be tolerated for several weeks, but dry periods for but a very short period. Limestone soil is its enemy; high calcium concentrations may be toxic to Drosera. Being very shade intolerant, Drosera can't do without a place in the sun. Shaded plants may not develop a rosette but instead have a more spindly habit. Woody vegetation invading bogs will outcompete it. Growing up to 10-20 cm high, Drosera compensates for its fragility by adapting to nutrient-poor conditions, which allows it to be very competitive and persistent in acid wetlands. It has colonized disturbed sites in bogs after peat mining, ditching, and burning. 1 Its insect-capturing capacities are enormous: one plant catches and digests an estimated 2000 insects per season!

 CONSTITUENTS Drosera contains tannic, citric, and malic acids, resin, iron, colouring matter [pepsinase], and naphtoquinone compounds. The presence of naphtoquinones appears to be typical for the Sundew family. They have been found in various species of all four genera. Austrian research suggests that the pharmacologically active naphtoquinones droserone, plumbagin, and [7-methyl]juglone are efficiency determining compounds of various Drosera species used for treating coughs. Naphtoquinones have also antibacterial properties.
MEDICINE The crushed leaves of Drosera species have been described as rubefacient and vesicant. The skin irritant activity may be attibutable to plumbagin and related naphtoquinones. There is also a theoretical risk of dermatitis caused by proteolytic enzymes. Drosera rotundifolia has been used to remove warts, corns, keratoses, and freckles in eastern and western North America. 2 It has anti-spasmodic, demulcent, expectorant actions. It appears to exert a relaxing effect on bronchial musculature. "Quincy in 1742 claimed that 'The secretion from the Sundew is reported to cure the toothache if held in the mouth; to cure madness if hung about the neck; tied about the wrist to cure ague; and to promote delivery if rubbed on the abdomen'."3
FOLKLORE On the Isle of Man the sticky-leaved common sundew was used as a love charm. Traditionally it was surreptitiously slipped into the clothing of the person who was to be attracted. On Colonsay some ladies mix the juice of sundew with milk so as to make a safe application to remove freckles and sunburns. In Scotland, among other places, the sundew was believed to make cattle and sheep ill. 4 People across Europe widely used Drosera as an aphrodisiac in wine and as a treatment against old age. The latter rested on the belief that the 'dew' on its leaves, which persists even in the hottest sun, possessed the property to endow longevity and youthfulness to those who drank it. In the 16th and 17th centuries, sundew was thought to be a remedy for melancholy. A sundew liqueur, known as Rosa Solis, was popular in Britain, France, and Germany during the 17th century for its reputedly fortifying and aphrodisiac effects. A similar tradition existed in Sweden, where an aquavit named Aqua rora solis was made from the plant, which was served as a morning bitter to start up the day. [The tradition of starting the day with a bitter, e.g. Gammeldansk - literally 'old Danish' - has persisted up to today.] Sundew leaves can curdle milk and were used in Sweden to make cheese. Under the poetic name 'Virgin Mary's Tears' the plant was highly regarded in Scandinavia for its calming effect on cough. This name is a christianized version of an older one, 'Freya's Tears', in allusion to Freya's sorrow over the departure of her consort Frey. Freya cried golden tears, which turned into droseras and became associated with fertility.

Main symptoms M Mistrust. • "All day long, uneasiness of disposition and anxiety, full of mistrust, as if he had to do with none but false people." • "Extremely uneasy, sad disposition, all day - he imagined he was being deceived by spiteful, envious people." [Hahnemann] • "The theme of Drosera is that of being stabbed in the back, of being deceived by one's own friends and yet, at the same time, great dependence on them. There is a feeling of weakness due to which he is dependent but at the same time, he feels his weakness is taken advantage of. This is a typical tubercular feeling. Drosera feels harassed by others and let down by his own friends. Even the cough is described in Phatak's M.M. as harassing." [Sankaran] • "Boy, age 10. ... He was very suspicious of me to begin with. I asked him about his new school. He replied that he liked his new school but ... 'It's bound not to last!' I asked him why. 'People always pick on me. At the last school it was always me who was punished, even though it wasn't my fault. On the school bus the kids used to tease me. I tried to ignore them but then I lost my temper and hit them. The teacher on the bus said I was always starting trouble. But I didn't start it! They all gang up on me. People are always nasty to me. They poke fun at me. Then I get angry and hit them. Then it's me that gets told off! It's not fair. I have a fear that someone bad will pick me up off the street and I'm not strong enough to get away.' ... Drosera is an insect-eating plant. The remedy was made with the trapped insect inside and this idea of deception leading to feeling trapped and attacked is very much part of the essence of Drosera."1 M Sadness. • "He is sad and dejected about the ills of life, which people cause one another and himself, respecting which he is anxious and concerned." • "He is dejected about the malice of others on all hands, and at the same time disheartened and concerned about the future." [Hahnemann] • "This remedy often applies to people who are too sensitive to others' maliciousness in a world where one must 'eat or be eaten'." [Grandgeorge] M ANXIETY when ALONE, with fear of ghosts. M RESTLESSNESS and difficult concentration. • "When reading he could not stick long to one subject - he must always go to something else." [Hahnemann] M OBSTINACY in executing resolutions; cannot be distracted. Insists upon carrying out his plans. G TUBERCULAR miasm. • "Drosera is closely related of course to the tubercular bone remedies, such as Silica, Tuberculinum, and Calc-phos.; it has, when indicated, a most striking effect; and it is the grandest tonic that I have ever come across, wherever it is the simillimum. My work lies largely among children and in marasmic and emaciated infants and older children with a tubercular background, I have found no other remedy work such startling changes in a comparatively short period as Drosera. ... It is unfortunate that the records I collected, on the value of Drosera in suitable cases of marasmus and malnutrition have been swallowed up and lost in the holocaust of war. They were cases in poor, under-nourished children of casual labourers, often out of work and on the dole, who could not be given extra nourishing food, extra milk, as the parents could not afford it. All the change that was made, was an occasional dose of Drosera 30 and the gain in weight followed, on the same diet as before, and in the same surroundings and without months of convalescence! ... Drosera in wasters. ... They hold nutrition clinics in London for the thousands of wasting children who simply will not get one, remain stunted, undersized and weakly. Frequently no particular cause can be discovered, the city life does not suit them, perhaps; they are put on extra milk, extra cod liver oil and malt, extra vitamin tablets, and yet many of them remain in a state of malnutrition; they cannot assimilate the extra food that is given them. I had a good few through my hands, as I said, and in many cases Drosera acted like a charm. It does not work out in the repertory; you have to go more by the family history, and if a case is going to do well on Drosera, it will do so at once; if it not act within a month, you have to look for another remedy."2 • "One should certainly think of Drosera for asthma with T.B. history." [Tyler] • "Sinus, gland or bone diseases of tuberculous nature, or in persons of tubercular family history." [Mathur] G GROWING PAINS in tubercular children. G Very chilly. • "Chill and shivering when at rest, seems to be cold everywhere, even in bed." • "Can't keep from shivering and feeling cold, although body is warm to touch." [Hering] G Profuse perspiration, esp. at night. G < Warmth. [Warm bed; after midnight.] > Open air.
G < Rest, LYING. > Walking, MOTION, continued motion.
G Scar tissue.
• "The three drugs one has seen dealing successfully with SCAR TISSUE are Graph., Sil. and Drosera; and where tuberculous scars are concerned, the greatest of these is Drosera." [Tyler]
P Violent SPASMODIC COUGH [deep, barking, hollow].
< After midnight. And [or ending in] gagging, vomiting, epistaxis, cold sweat. Followed by loquacity. • "Deep down in the fauces [and on the soft palate] a rough, scraping sensation of dryness exciting short cough, with yellow slimy expectoration and hoarseness of the voice, so that it is only with an effort than he can speak in a deep bass tone; at the same time he feels an oppression of the chest, as if something there kept back the air when he coughed and spoke, so that the breath could not be expelled [lasting several days]." • "Tightness of chest, esp. whenever he speaks, even at every word - the throat was contracted; he felt no tightness of chest when walking." [Hahnemann] • "The Drosera cough is induced by a tickling or crawling sensation in the larynx; it is violent and occurs in paroxysms accompanied by choking, vomiting and cold sweats. It is usually worse on first lying down and in the second half of the night at about 2 a.m. The cough is aggravated by talking, by eating and by taking cold food or fluids. Typically the sufferer holds on to the chest with both hands to ease the distressing cough." [Gibson] P Hoarse, deep, toneless voice. P Stiffness and inflexibility of ankles.
