Raccoon Dog

The Raccoon Dog is native to East Asia; it was brought to European Russia at the beginning of the nineteenth century and has since spread to other parts of Europe. Because of the white area around its snout, it strongly resembles a Raccoon, but the black band on its face is broken into two parts. The forehead is light, and an even lighter, almost white area stretches over the entire neck. The ears have dark borders, the back is mottled grey with dark stripes. 

The chest, belly, and legs are black, the tail is unstriped and dark on top, light underneath. The legs are all the same length. Raccoon Dog is about 60–80 cm long, and the tail measures up to 20 cm. Its height at the shoulder is 20–30 cm, and it weighs up to 10 kg. The Raccoon Dog’s thick fur exaggerates its true size. Raccoon Dogs live in deciduous or mixed forest with thick underbrush, usually near water or swamps, and in open landscapes with wet areas and areas with bush cover. 

It is not a shy animal, so you might also see it near or in inhabited areas.Raccoon Dogs do not hibernate, but like Eurasian Badgers, they remain in their den for several days if there is a severe frost or heavy snow. The prints of Raccoon Dog always show four toes set an equal distance from the central pad print, as well as clear claw marks. 

The front footprint is 4–5.5 cm long and about 4.5 cm wide, the rear footprints are somewhat smaller, 4–4.5 cm long and about 3.5 cm wide; the stride is about 40–60 cm. The tracks can resemble those of a fox, although the latter are more elongated. There is essentially no visible difference between the tracks of a domestic dog and those of a Raccoon Dog, and the latter may also be confused with the tracks of a domestic cat, even though the cat’s footprints never show claw prints. 

A male and female often hunt together, and one often sees the prints of two animals in the same place. The footprints are often found on the muddy shores of lakes or streams or in marshy areas. At the water’s edge, one may often also find paths that are regularly used by the animals.A Raccoon Dog can dig its own den, but it will also use old Eurasian Badger and fox dens, or live in natural cavities: in hollow trees, under roots, or between stones and rocks. One will almost always find the remains of prey close by. 

Raccoon Dogs live in family groups in established territories, which are, however, not defended vigorously. Like Raccoons and Eurasian Badgers, Raccoon Dogs are omnivores, but they consume mainly small rodents. The scat is somewhat twisted, 5–8 cm long, 1.5– 2 cm thick, and often contains much hair. It resembles domestic dog scat, but is left in piles—in latrines near the burrow or along the edge of territory. 

Beware! Raccoon Dog scat should not be touched since it can contain eggs of the dwarf tapeworm (transmitted by foxes), which can be dangerous to human beings. In many places in eastern Europe, this is the reason mushrooms and berries are not gathered in the wild.

CALAMUS (Acorus calamus var. angustatus)

 FAMILY Araceae

SYNONYMS Calamus aromaticus, sweet flag, sweet sedge, sweet root, sweet rush, sweet cane, sweet myrtle, myrtle grass, myrtle sedge, cinnamon sedge. GENERAL DESCRIPTION A reed-like aquatic plant about 1 meter high, with sword-shaped leaves and small greenish-yellow flowers. It grows on the margins of lakes and streams with the long-branched rhizome immersed in the mud. The whole plant is aromatic.

DISTRIBUTION Native to India; the oil is mainly produced in India and Russia and to a lesser extent in Europe (except Spain), Siberia, China, Yugoslavia, and Poland (Polish and Yugoslavian oils have a uniform lasting scent).

OTHER SPECIES Not to be confused with the yellow flag iris which it resembles in appearance; they are botanically unrelated. There are several other varieties of aromatic sedge, mostly in the east, for example, Calamus odoratus is used in India as a medicine and perfume.

HERBAL/FOLK TRADITION The name derives from the Greek calamos meaning ‘reed’. The properties of the herb are mainly due to the aromatic oil, contained largely in the root. It used to be highly esteemed as an aromatic stimulant and tonic for fever (typhoid), nervous complaints, vertigo, headaches, dysentery, etc. It is still current in the British Herbal Pharmacopoeia, for ‘acute and chronic dyspepsia, gastritis, intestinal colic, anorexia, gastric ulcer.’18 In Turkey and especially in India (where it is valued as traditional medicine), it is sold as a candied rhizome for dyspepsia, bronchitis, and coughs. 

ACTIONS Anticonvulsant, antiseptic, bactericidal, carminative, diaphoretic, expectorant, hypotensive, insecticide, spasmolytic, stimulant, stomachic, tonic, vermifuge.

EXTRACTION Essential oil by steam distillation from the rhizomes (and sometimes the leaves). 

CHARACTERISTICS A thick, pale yellow liquid with a strong, warm, woodyspicy fragrance; poor quality oils have a camphoraceous note. It blends well with cananga, cinnamon, labdanum, olibanum, patchouli, cedarwood, amyris, spice and oriental bases.

PRINCIPAL CONSTITUENTS Beta-asarone (amounts vary depending on source: the Indian oil contains up to 80 per cent, the Russian oil a maximum of 6 per cent), also calamene, calamol, calamenene, eugenol and shyobunones. 

SAFETY DATA Oral toxin. The oil of calamus is reported to have carcinogenic properties.

AROMATHERAPY/HOME USE None. ‘Should not be used in therapy, whether internally or externally.’
