[amazon_link asins=’B015FVVIGS,B06XF4W838,B01CDK4R4O,B00K42LPCQ,B01H6KNN0K,B01N2TEH4C,B00KCUS2FS,B06XF5372Z’ template=’ProductCarousel’ store=’finmeacur-20′ marketplace=’US’ link_id=’78a6b604-4a75-11e7-88d9-59cd5a3c72bb’]

Botanical Name :Mentha citrata
Family:    Lamiaceae
Genus:    Mentha
Species:M. citrata
Kingdom:Plantae
Order:    Lamiales

Synonym: Mentha odorata.

Common Names: Bergamot mint, Eau-de-cologne Mint, Horsemint, Lemon Mint, Lime Mint, Orange Mint, Pineapple Mint, Su Nanesi, Water Mint, Wild Water Mint, Yerba Buena

Habitat : :Mentha citrata is found in wet places in Staffordshireand Wales, though very rarely, but is often cultivated in gardens.It is found  on the sides of ditches, roadsides etc in S. England.

Description:
Mentha citrata is a perennial herb, growing to a height of about a feet.The whole plant is smooth, dotted with yellow glands and is of a dark green colour, generally tinged with purple, especially the margins of the leaves, which are finelly toothed. There are very conspicuous lines of yellow glands on the purple calyx.It blooms during August to October.

This Mint has a very pleasant, aromatic, lemon-like odour, somewhat resembling that of the Bergamot Orange, or that of the Oswego Tea (Monarda didyma), also called Bergamot, and its leaves like those of the latter can be employed in pot pourri.

Cultivation & Propagation: A natural hybrid, M. aquatica x M. spicata found in moist soils on the sides of ditches, roadsides etc in S. England.

Seed – sow spring in a cold frame. Germination is usually fairly quick. Prick out the seedlings into individual pots when they are large enough to handle and plant them out in the summer. Mentha species are very prone to hybridisation and so the seed cannot be relied on to breed true. Even without hybridisation, seedlings will not be uniform and so the content of medicinal oils etc will vary. When growing plants with a particular aroma it is best to propagate them by division. Division can be easily carried out at almost any time of the year, though it is probably best done in the spring or autumn to allow the plant to establish more quickly. Virtually any part of the root is capable of growing into a new plant. Larger divisions can be planted out direct into their permanent positions. However, for maximum increase it is possible to divide the roots up into sections no more than 3cm long and pot these up in light shade in a cold frame. They will quickly become established and can be planted out in the summer.

Edible Uses:
Leaves – raw or cooked. Used as a flavouring in salads or cooked foods. A very pungent flavour, the leaves of the true eau-de-cologne mint are too aromatic for most tastes, though the cultivar “Basil” has an excellent flavour and makes a very good substitute for basil in pesto. A herb tea is made from the fresh or dried leaves.

Medicinal Uses:
Mentha citrata or Eau de Cologne mint, like many other members of this genus, is often used as a domestic herbal remedy, being valued especially for its antiseptic properties and its beneficial effect on the digestion. Like other members of the genus, it is best not used by pregnant women because large doses can cause an abortion. The leaves and flowering plant are anodyne, antiseptic, antispasmodic, carminative, cholagogue, diaphoretic, refrigerant, stomachic, tonic, vasodilator. A tea made from the leaves has traditionally been used in the treatment of fevers, headaches, digestive disorders and various minor ailments. The medicinal uses of this herb are more akin to lavender (Lavandula spp) than the mints. It is used to treat infertility, rapid heartbeat, nervous exhaustion etc. The leaves are harvested as the plant comes into flower and can be dried for later use. The essential oil in the leaves is antiseptic, though it is toxic in large doses.

A tea made from the fresh or dried leaves has traditionally been used:

*For stomach aches, nausea, parasites and other digestive disorders

*For nerves and sick stomach

*For fevers and headaches.

Other Uses: An essential oil obtained from the whole plant is a source of lavender oil which is used in perfumery. It is also used in oral hygiene preparations, toiletries etc. Formerly used as a strewing herb, the plant repels insects, rats etc. Rats and mice intensely dislike the smell of mint. The plant was therefore used in homes as a strewing herb and has also been spread in granaries to keep the rodents off the grain.

Known Hazards:  Although no specific mention has been seen for this sub-species, it should be noted that, in large quantities, the closely allied M. x piperita vulgaris can cause abortions, especially when used in the form of the extracted essential oil, so it should not be used by pregnant women.

Sanicula Europaea

[amazon_link asins=’B0032JZA0Q,B015J5V1MQ,B00DL0IEOU,B00DL0G9MY’ template=’ProductCarousel’ store=’finmeacur-20′ marketplace=’US’ link_id=’3e9842cd-4a59-11e7-9816-1b378c346e12′]

Botanical Name : Sanicula Europaea
Order: Apiales
Family: Apiaceae
Genus: Sanicula
Species: S. europaea
Kingdom: Plantae

Synonyms: Poolroot. Self-Heal.

Common Names :Sanicle, Wood sanicle

Habitat:  Wood Sanicle  is most abundant in the middle and north of Europe and is found on the mountains of tropical Africa. It is the only representative in this country of the genus Sanicula, to which very few species are assigned. It grows  in woods and thickets and damp moist places, and generally distributel over the British Isles.It is widespread in shady places woodland across Europe.

Description:
Wood Sanicle is an umbelliferous perennial plant.The root-stock (the short underground stem from which each year’s new stalks grow upward) is shortly creeping and fibrous, with a few thick, brownish scales at the top, the remains of decayed leafstalks. The stem, erect, 8 inches to 2 feet high, is simple, often leafless or with a single leaf. The radical leaves are on stalks 2 to 8 inches long, the leaves themselves palmately three to five partite and divided nearly to the base of the leaf, the lobes, or divisions, often three-cleft again. The leaves are heartshaped at the base near the stalk and toothed like a saw.

CLICK & SEE THE PICTURES

The flowers are in umbels. Each little group, or umbellule, forms a hemispherical head. The little stalks, each bearing a head of flowers, join together at one spot again to form what is termed a compound or general umbel, as in most plants of this order. In the case of the Sanicle, the umbel is said to be irregular, as the converging stalks forming these rays are often divided into two or three prongs. The flowers are pinkish-white, 1/16 inch across, the outer flowers of the umbellules being without stamens; the inner, without pistils. They blossom in May and June and are succeeded in August by roundish seeds, which are covered with prickles, causing them to adhere to everything they touch.

The plant is glabrous and bright green, the leaves paler beneath and the stems often reddish.

The origin of the name of this genus is the Latin word sano (I heal or cure), in reference to the medicinal virtues.

 Cultivation:   
Succeeds in any moist moderately fertile well-drained soil in sun or semi-shade. Strongly dislikes poor thin soils. Prefers a loamy or calcareous soil. The seeds are covered with little prickles, enabling them to become attached to anything that brushes against them and thus distributing the seed.

Propagation           
Stratification improves the germination rate. If possible sow the seed in the autumn, sow stored seed as early in the year as possible. It is best to sow the seed in situ in a woodland soil under trees If seed is in short supply it is probably wise to sow it in pots of woodland soil in a shady place in a cold frame. When they are large enough to handle, prick the seedlings out into individual pots and grow them on in a shady position in the greenhouse for their first winter. Plant them out into their permanent positions in late spring or early summer, after the last expected frosts. Division in spring. Larger divisions can be planted out direct into their permanent positions. We have found it best to pot up the smaller divisions and grow them on in a lightly shaded position in a cold frame, planting them out once they are well established in the summer.

Edible Uses:  Leaves and young shoots – cooked. They contain saponins so should not be eaten in large quantities. A famine food, it is only used when all else fails.

Medicinal Uses:
Part Used:  The whole herb, collected in June and dried. Gather the herb only on a fine day, in the morning, when the sun has dried off the dew.

Constituents:  As yet no analysis has been made of this plant, but evidence of tannin in its several parts is afforded by the effects produced by the plant.

In taste it is at first very bitter and astringent, afterwards acrid, and probably partakes of the poisonous acridity which is so frequent in the Umbelliferae. In the fresh leaves, the taste is very slight, but considerable in the dry leaves, and in the extract made from them.

Astringent, alterative. Sanicle is usually given in combination with other herbs in the treatment ofblood disorders, for which it is in high esteem.

As an internal remedy, it is of great benefit in all chest and lung complaints, chronic coughs and catarrhal affections, inflammation of the bronchii, spitting of blood, and all affections of the pulmonary organs.

As an alterative, it has a good reputation, and it is useful in leucorrhoea, dysentery, diarrhoea, etc.

It effectually cleanses the system of morbid secretions and leaves the blood healthier and in better condition. The infusion of 1 OZ. to a pint of boiling water is taken in wineglassful doses.

Sanicle is used as a gargle in sore throat, quinsy, and whenever an astringent gargle is required. Culpepper mentions the use of Sanicle for disease of the lungs and throat, and recommends the gargle being made from a decoction of the leaves and root in water, a little honey being added.

In scald-head of children and all cases of rashes, the decoction or infusion forms an admirable external remedy.

Sanicle is popularly employed in France and Germany as a remedy for profuse bleeding from the lungs, bowels, and other internal organs and for checking dysentery, the fresh juice being given in tablespoonful doses.

Known Hazards:  The leaves contain saponins. Although toxic, saponins are very poorly absorbed by the body and so tend to pass through without causing harm, they are also destroyed by thorough cooking. Saponins are found in many plants, including several that are often used for food, such as certain beans. It is advisable not to eat large quantities of food that contain saponins. Saponins are much more toxic to some creatures, such as fish, and hunting tribes have traditionally put large quantities of them in streams, lakes etc in order to stupefy or kill the fish.

Opoponax chironium

[amazon_link asins=’B00HTQG840,B00NBBRE40,B016UPY5YU,B06Y5TL84M,B01L11B21M,B009PSRPLA,B00KWI33MM,B00UUB0S6U,B0176YOIEQ’ template=’ProductCarousel’ store=’finmeacur-20′ marketplace=’US’ link_id=’42e584c3-29ca-11e7-9ba0-d1023aab1acf’]

Botanical Name : Opoponax chironium
Family: Apiaceae
Genus:     Opopanax
Species: O. chironium.
Kingdom: Plantae
Order:    Apiales

Synonym: Pastinaca Opoponax.

Common Names:Sweet myrrh or Bisabol myrrh

Habitat; Opoponax chironium  thrives in warm climates like Iran, Italy, Greece, Turkey and Somalia, but also grows in cooler climates. Some view opopanax grown in cooler climates as being of inferior quality.

Description:
Opoponax chironium is a perennial herb, with a thick, fleshy root, yellowish in colour. It has a branching stem growing about 1 to 3 feet high, thick and rough near the base. Leaves pinnate, with long petioles and large serrate leaflets, the terminal one cordate, the rest deficient at the base, hairy underneath. The flowers, yellowish, are in large, flat umbels at the top of the branches. The oleo resin is procured by cutting into the stem at the base. The juice that exudes, when sun-dried, forms the Opoponax of commerce. A warm climate is necessary to produce an oleo gum resin of the first quality; that from France is inferior, for this reason. In commerce it is sometimes found in tears, but usually in small, irregular pieces. Colour, reddish-yellow, with whitish specks on the outside, paler inside. Odour, peculiar, strongly unpleasant. Taste, acrid and bitter. It is inflammable, burning brightly.

Medicinal Uses:

Part Used: Concrete juice from the base of stem.

Constituents:  Gum-resin, starch, wax, gum, lignin, volatile oil, malic acid, a slight trace of caoutchouc.

Antispasmodic, deobstruent. The resin has been used in the treatment of spasms, and, before that, as an emmenagogue, in the treatment of asthma, chronic visceral infections, hysteria and hypochondria. Opopanax resin is most frequently sold in dried irregular pieces, though tear-shaped gems are not uncommon.

Other Uses:
A consumable resin can be extracted from opopanax by cutting the plant at the base of a stem and sun-drying the juice that flows out. Though people often find the taste acrid and bitter, the highly flammable resin can be burned as incense to produce a scent somewhat like balsam or lavender.
It is employed in perfumery.

Botanical Name :  Polypodiurn vulgare
Family: Polypodiaceae
Genus: Polypodium
Species: P. vulgare
Kingdom: Plantae
Division: Pteridophyta
Class: Polypodiopsida /Pteridopsida (disputed)
Order: Polypodiales

Synonyms: Polypody of the Oak. Wall Fern. Brake Root. Rock Brake. Rock of Polypody. Oak Fern.

Common Name :common polypody

Habitat :The common polypody is very common in France, where it is found up to an altitude of 2,000 metres (6,600 ft). It is also quite common in Scandinavia and Carpathian Mountains. It is present but less commonly found around the Mediterranean region.
It is an introduced species in New Zealand, that has begun to spread into the wild as an invasive species. It grows on Rocks, walls and trees, as well as on the ground, in a variety of habitats but especially in humid shady conditions.

Description:

Polypodium vulgare is an evergreen fern developing in isolation from along a horizontal rhizome. The fronds with triangular leaflets measure 10 to 50 centimetres.
It is hardy to zone 3. It is in leaf 12-Jan.

They are divided all the way back to the central stem in 10 to 18 pairs of segments or leaflets.

The leaflets become much shorter at the end of the frond. The leaflets are generally whole or slightly denticulated and somewhat wider at their base, where they often touch each other. They have an alternating arrangement, those on one side being slightly offset from those on the other side. The petioles have no scales.

The sori are found on the lower side of the fronds and range in colour from bright yellow to orange. They became dark grey at maturity.

*Period of sporulation: July to September.
*Mode of dissemination: anemochory (wind dispersal).

P. vulgare is an allotetraploid species of hybrid origin, its parents being the diploids Polypodium appalachianum and Polypodium glycyrrhiza.

Cultivation:
Easily grown in most light soils. Prefers a soil of leaf mould and a cool but not too moist clay. Prefers a cool damp shady position. Thrives in dry shade. Established plants are drought tolerant. They grow well on drystone walls. Plants often grow as epiphytes. Members of this genus are rarely if ever troubled by browsing deer. A rather variable plant, it is considered to be an aggregate species of several very similar species. Only the roots should be planted, the rhizome being fixed to the surface of the soil.

Propagation:                                            
Spores – best sown as soon as they are ripe, though they can also be sown in the spring. Sow them on the surface of a humus-rich sterilized soil. Keep the compost moist, preferably by putting a plastic bag over the pot. Pot on small clumps of plantlets as soon as they are large enough to handle and keep humid until they are well established. Do not plant outside until the ferns are at least 2 years old and then only in a very well sheltered position. Division. This is best done in the spring but it succeeds at most times of the year

Edible Uses:     
Edible Parts: Root.

Root. Very sweet, it contains sugars, tannin and oils. It is used as a liquorice adulterant. The root has a unique, rather unpleasant odour and a sweet (cloying) flavour at first though it quickly becomes nauseating. The root contains 15.5% saccharose and 4.2% glucose.

Medicinal Uses:
Part Used Medicinally : The root, which is in perfection in October and November, though it may be collected until February. It is used both fresh and dried, and the leaves are also sometimes used.

Polypody stimulates bile secretion and is a gentle laxative. In European herbal medicine it is traditionally used as a treatment for hepatitis and jaundice and as a remedy for indigestion and loss of appetite. It should not be used externally since it can cause skin rashes. The root is alterative, anthelmintic, cholagogue, demulcent, diuretic, expectorant, pectoral, purgative, tonic. It can be used either fresh or dried and is best harvested in October or November, though it can be collected until February. The leaves can also be used but are less active. A tea made from the roots is used in the treatment of pleurisy, hives, sore throats and stomach aches and as a mild laxative for children. It was also considered of value for lung ailments and liver diseases. The poulticed root is applied to inflammations. A tea or syrup of the whole plant is anthelmintic.

Other Uses:  
Insecticide;  Potash.
Plants can be grown as a ground cover in a shady position. They form a spreading carpet and are best spaced about 30cm apart each way. The ash of burnt leaves is rich in carbonate of potash

Known Hazards :  Although we have found no reports of toxicity for this species, a number of ferns contain carcinogens so some caution is advisable[200]. Many ferns also contain thiaminase, an enzyme that robs the body of its vitamin B complex. In small quantities this enzyme will do no harm to people eating an adequate diet that is rich in vitamin B, though large quantities can cause severe health problems. The enzyme is destroyed by heat or thorough drying, so cooking the plant will remove the thiaminase.

Rubia tinctorum

[amazon_link asins=’B00YPQ097Y,B00K1I7SKQ,B00088Q9CW,B01N5GLKQE,B074J5FQL4,B0071HIGUG,B008X8TMS2′ template=’ProductCarousel’ store=’finmeacur-20′ marketplace=’US’ link_id=’e9e3d367-7e43-11e7-a31a-63802d5d8a75′]

Botanical Name :Rubia tinctorum
Family: Rubiaceae
Tribe:     Rubieae
Genus:     Rubia
Species: R. tinctorum
Kingdom: Plantae
Order:     Gentianales

Synonyms: Krapp. Dyer’s Madder. Robbia.
(French) Garance.   Galium rubia. Rubia acaliculata. Rubia iberica. Rubia sativa.

Common Names :Madder or Common madder

Habitat:  Rubia tinctorum  is native to Southern Europe, including southern Britain, and Mediterranean countries. It grows on neglected ground, hedgerows and among rubble.

Description:
Rubia tinctorum is an evergreen Perennial plant growing to 1 m (3ft 3in) by 1 m (3ft 3in) at a medium rate.The evergreen leaves are approximately 5–10 cm long and 2–3 cm broad, produced in whorls of 4–7 starlike around the central stem. It climbs with tiny hooks at the leaves and stems. The flowers are small (3–5 mm across), with five pale yellow petals, in dense racemes, and appear from June to August, followed by small (4–6 mm diameter) red to black berries. The roots can be over a metre long, up to 12 mm thick and the source of red dyes known as rose madder and Turkey red. It prefers loamy soils (sand and clay soil) with a constant level of moisture. Madder is used as food plants for the larvae of some Lepidoptera species including the Hummingbird Hawk Moth.

CLICK & SEE THE PICTURES
It is hardy to zone 6. It is in leaf 12-Jan It is in flower in June, and the seeds ripen in September. The flowers are hermaphrodite (have both male and female organs)

Cultivation:   
Prefers a light sandy soil in full sun. Plants grown in fertile well-limed soils produce more pigment in the root. This plant was at one time widely cultivated for the red dye obtained from its roots, this dye is now manufactured chemically. However, it is still cultivated in Europe as a medicinal dye plant. The plant produces many side roots that can travel just under the surface of the soil for some distance before sending up new shoots. This species is closely related to R. peregrina.

Propagation:    
Seed – best sown as soon as it is ripe in a cold frame. Stored seed can be very slow to germinate. Prick out the seedlings when they are large enough to handle and grow them on in light shade in the greenhouse for the first year. Plant them out into their permanent positions in early summer. Division in spring or at any time in the growing season if the divisions are kept well watered until established. Larger divisions can be planted out direct into their permanent positions. We have found it best to pot up the smaller divisions and grow them on in a lightly shaded position in a cold frame, planting them out once they are well established in the summer

Medicinal Uses:

Parts : used :root
Constituents:The root contains rubian, rubiadin, ruberythric acid, purpurin, tannin, sugar and especially alizarin. Pseudopurpurin yields the orange dye and xanthopurpurin the yellow. The astringent taste, slight odour and red colour, are imparted to water or alcohol.

The most interesting of the colouring substances is the alizarin, and this is now termed dihydroscyanthraquinone. This occurs as orange-red crystals, almost insoluble in water, but readily soluble in alcohol, ether, the fixed oils and alkaline solutions. The alcoholic and aqueous solutions are rose-coloured, the ethereal, golden-yellow; the alkaline, violet and blue when concentrated, but violet red when sufficiently diluted. A beautiful rose-coloured lake is produced by precipitating a mixture of the solutions of alizarin and alum.

Alizarin was recognized by Graebe and Liebermann, in 1868, as a derivative of anthracene – a hydrocarbon contained in coal-tar, and in the same year they elaborated a method for preparing it commercially from anthracene. Upon this arose rapidly a great chemical industry, and the cultivation of Madder has, of course, decreased correspondingly until it may be said that the coaltar products have entirely displaced the natural ones.

The root is aperient, astringent, cholagogue, diuretic and emmenagogue. It is taken internally in the treatment of kidney and bladder stones. The root is seldom used in herbal medicine but is said to be effective in the treatment of amenorrhoea, dropsy and jaundice. The roots are harvested in the autumn from plants that are at least 3 years old. They are peeled and then dried. When taken internally the root imparts a red colour to the milk, urine and bones, especially the bones of young animals, and it is used in osteopathic investigations.

When taken into the stomach it imparts a red colour to the milk and urine, and to the bones of animals without sensibly affecting any other tissue. The effect is observed most quickly in the bones of young animals and in those nearest to the heart. Under the impression that it might effect some change in the nervous system, it has been prescribed in rachitis (rickets), but without noticeable favourable results. Dosage, 1/2 drachm three or four times daily.

 
Other Uses:
A very good quality red dye is obtained from the roots. Some reports say that 2 year old roots are used in the spring and autumn whilst others say that 3 year old roots are used. The roots can be dried for later use. The dye can also be extracted from the leaves. It has been used since ancient times as a vegetable red dye for leather, wool, cotton and silk. For dye production, the roots are harvested in the first year. The outer brown layer gives the common variety of the dye, the lower yellow layer the refined variety. The dye is fixed to the cloth with help of a mordant, most commonly alum. Madder can be fermented for dyeing as well (Fleurs de garance). In France, the remains were used to produce a spirit as well. This dye is also used medicinally. The leaves and stem are prickly, the whorls of leaves having spines along the midrib on the underside. This feature enables them to be used for polishing metalwork

Known Hazards: Potential to cause cancers, particularly liver and kidney. From the information currently available it is not recommended as a herbal medicine .
