TRAILING OR MOUNTAIN AZALEA: HISTORY AND HEALTH BENEFITS OF TRAILING AZALEAS

TRAILING OR MOUNTAIN AZALEA, KALMIA PROCUMBENS  

This alpine plant grows in the Arctic and in Scotland in the British Isles. It can be found growing with Iceland moss, Mountain club moss and wild strawberries. It was formerly called Loiseleuria procumbens, but has recently been moved to the Kalmia genus. This means that it is now in the same genus as Kalmia latifolia, Mountain laurel which is indigenous to North America. Interestingly trailing azaleas are the only Kalmia genus not native to North America.

  As a member of the Ericaceae or heather (ling) family, it is related to the Greek strawberry tree, the strawberry tree, yellow bird’s nest, wintergreen (Gaultheria procumbens), round-leaved wintergreen, bilberries, blueberries and cranberries. However the wintergreens have now been moved into their own separate families.                                           

  The rootstock of this plant is wide, with the majority of the plant being under the ground. The plants can live for between fifty and sixty years.

  Nicholas Culpeper describes the flowers as red, and there are some, but these are rarer than the plants with pink flowers. In Culpeper’s day I suppose they grew in parts of Britian other than Scotland. He was the great English herbalist who wrote his Herball in the 17^th century. This is what he said about the medicinal properties of the trailing azalea.

“Government and virtues. It is a plant of Mercury, and has a pleasing aromatic smell, resembling that of lemons; and is cordial and strengthening.

 It comforts the head and stomach, removes palpitations of the heart, helps the vertigo, or giddiness and swimmings in the head, and is greatly extolled by many, as a specific in nervous and hypochondrical disorders.”

  Today it is not used in medicine it would appear from my research.

   The Kalmia genus has an interesting history. It was named by Karl Linnaeus, often referred to as the Father of Botany, for his student, Pehr Kalm (1715-1779), who was from Finland but studied under Linnaeus in Uppsala. The Swedish Academy of Sciences, on the recommendation of Linnaeus, sent Kalm to North America to find plants that could be grown in Sweden.

  Kalm was accompanied in North America by the Canadian Gaultherias, and it was Kalm who named wintergreen (Gaultheria procumbens) after his Canadian companion.

   Linnaeus named one of the North American shrubs that Kalm took back to Sweden, Mountain laurel Kalmia latifolia, after him, and so a genus was born to honour Pehr Kalm.

DRAGONFRUIT: HEALTH BENEFITS AND USES OF DRAGONFRUIT

DRAGONFRUIT, PITAYA, HYLOCEREUS UNDATUS  

Dragonfruit is the fruit of a night-flowering cactus which produces the largest flowers of any cactus, which are a foot long and ten inches wide. As a member of the Cactaceae family of plants dragonfruit is related to the cactus which bears prickly pears, but this fruit is huge in comparison to a prickly pear. It originated in South America but no wild plants have been so far found. 

It is now cultivated in several Asian countries including Malaya and the Philippines.

  At first sight the plant may not appear to be a cactus as it has long branched trailing ribbons of green with spikes on the ribs. It is three sided and can produce aerial roots which help it to climb trees and trellises. It is quite happy hanging from pots in cultivation and can also creep along the ground.

  The fruit of this variety of dragonfruit is red-skinned with white flesh full of black edible seeds which contain the fats and protein in the fruit. You slice open the fruit and scoop out the flesh. In other species of plant such as Selinocereus megalanthus, the fruit has a yellow skin and white flesh, while there is also a red pulp variety which comes from Hylocereus polyrhizus.

  The flesh can be eaten raw or cooked in jellies, jams and preserves, or you can use it raw in fruit salads or in smoothies and so on. It is said to taste a little like a kiwi fruit or perhaps a watermelon.

  This fruit is being called a wonder fruit, although it has about as many vitamins and minerals as a watermelon and contains about as much water. 

The “wonder” of it is that it is rich in photoalbumins which have potent antioxidant properties; hence it is good for the cardiovascular system and to protect the body from the scavenging free-radicals which can cause cancer.                                           

  It contains small amounts of the B-complex vitamins B3 and B1, but does contain a slightly higher amount of B2 (riboflavin) It also contains vitamins A in the form of carotene and C in the form of ascorbic acid. As for minerals it has calcium, phosphorous and iron.

 These small amounts of vitamins and minerals make the 100 gram serving good for people on a weight loss diet as that portion only has 60 calories, and of course fruit is very good for boosting the immune system and the B-complex vitamins and the others, make the fruit good for the skin, eyes, hair, bones and teeth.

  However it won’t on its own help you to lose weight, and like any other fruit it is definitely good for your health. That being said, it is higher than other fruit in photoalbumins perhaps, so does have potent antioxidant properties, giving it an edge over other fruit.

  

COMMON AND MOUNTAIN CLUB MOSS: HEALTH BENEFITS USES AND POSSIBLE FUTURE BENEFITS OF COMMON AND ALPINE CLUB MOSS

common club moss

COMMON CLUB MOSS, LYCOPODIUM CLAVATUM, MOUNTAIN OR ALPINE CLUB MOSS, DIPHASIASTRUM ALPINUM  

Common club moss is native to the Arctic and Europe and along with mountain club moss can be found in the British Isles. Both mosses are actually ferns, with common club moss resembling asparagus spears. Both these ferns are in the Lycopodiaceae family of plants. Lycopodium means wolf’s foot in Latin and the common club moss is sometimes called wolf’s claw (clavatum means claw). The two mosses look similar, although Mountain club moss is used in traditional medicine as an anti-inflammatory.

  The ancient Physicians of Myddfai employed mountain club moss in the following remedy for a woman who was unable to conceive:-

“A sterile woman may have a potion prepared for her by means of the following herbs, viz:—St. John's wort, yew, agrimony, amphibious persicaria, creeping cinque foil, mountain club moss, orpine and pimpernel, taking an emetic in addition.”

Alpine club moss

(The physicians wrote their remedies between the years 800 and 1800 in Wales; this is one of the earlier remedies.)                                                                                              

  Traditionally the common club moss was used for stomach problems and as a diuretic, to remove stones from the bodily organs and for other kidney problems. In the 17^th century the use of the whole plant stopped and only the spores were used.

  The spikes of the plant mature in the months of July and August and the spores have to be shaken out of the plant and this ‘dust’ is used for a number of ailments. For example it was used on the skin for eczema and other skin problems as well as to stop itchiness. It was given to people with rabies to stop their spasms, and also for gout and scurvy. It was also used for rheumatism and applied to wounds as a healing and cleansing agent.

Alpine club moss

  The powder has the ability to repel water and to stop things sticking together so it has been used for condoms to prevent the latex sticking together. The plant has also been used as a mordant in dying and the stems were used for matting. The spores have also been used in fireworks and to make artificial lightning. They also have uses in the food industry because of their water and liquid repellant properties. However they can be an allergen and workers in condom factories have developed asthma from using these spores.

Alpine club moss

  There has been some clinical research done on these plants but none that is conclusive. They have been touted as being good for Alzheimer’s patients in that they improve memory. 

They have also been tested as anticancer material but again there is no conclusive evidence to support their use as yet.                                        

They can be helpful in respiratory problems it seems and traditionally they have been used to control internal bleeding. They may dispel stones from the urinary tract, and seem to help with skin problems. They are also a diuretic.

  However more research need to be carried out on these plants, and this is unlikely to be done in the case of the mountain club moss as in some countries it is listed as a threatened species.

 

 

   

ROYAL FERN: SUPERSTITIONS, HEALTH BENEFITS AND USES OF ROYAL FERN

ROYAL FERN, OSMUNDA REGALIS

The royal fern is the tallest native fern in the British Isles, and can grow to heights of ten feet in moist, shady places. It is also called the flowering fern, as it has showy seeds in June through to August. It is native to Europe, North Africa and Asia and a subspecies flourishes in North America. 

It is one of my favourite ferns, as it grew profusely in Wales and I could easily hide from my long-suffering grandfather in those tall ferns.

  The name Osmunda probably comes from the Saxon os (meaning house) and mund, peace, so it was a symbol of domestic peace. Another etymological explanation is that is comes from the Latin with os meaning bone, and mundare meaning to cleanse. This would refer to its use for diseases of the bones caused primarily by malnutrition (e.g. rickets). Regalis means royal or regal in Latin. It is a member of the Osmundaceae family of plants.

Like bracken seeds which were supposed to make the holder of these invisible, there is also a legend regarding the sporangia (seeds or spores) of the Royal fern. It was supposed to have magical powers, and to uproot a fern, or at least to harvest its seeds, one had to draw a circle around oneself and the fern, and then withstand the onslaught of demons. However it was worth the fright, because a person who had the fern seeds could command demons and defeat them they also would have wishes granted and would also be able to understand the language of trees. Also secrets would be revealed to them. Clearly it was worth braving a few demons to obtain the fern, although this could only be done on the evening before Easter. The fronds are fertile in April so this makes some sense.

  The fronds were once combined with wild ginger and given to children who suffered from convulsions caused by parasitical worms.                                    

  Hairs of the Royal fern were formerly  mixed with wool to make cloth, while the roots were the source of Osmunda fibre, which was very popular for potting orchids.

  The root of the Royal fern is mucilaginous and soothes the mucous membranes, so was used in a decoction for jaundice, to remove stones from the internal organs, and a conserve made from the root was given in cases of rickets. It was also recommended for lumbago and the young fronds were made into an ointment which was used on bruises, dislocated bones and wounds. The fronds were used externally as a poultice for rheumatism.

   John Gerard, writing in the 16^th century had this to say about the royal fern:-

“The root and especially the heart or middle thereof, boiled or else stamped and taken with some kind of liquor, is thought to be good for those that are wounded, drybeaten and bruised, that have fallen from some high place.”

  He is a little vague as his wisdom came from older more ancient herbalists. Nicholas Culpeper, writing his Herball in the 17^th century had this to say about the medicinal properties of the Royal fern:-

“Government and virtues. Saturn owns the plant. This hath all the virtues mentioned in the former ferns, and is much more effectual than they, both for inward and outward griefs, and is accounted singular good in wounds, bruises, or the like. The decoction to be drank or boiled into an ointment of oil, as a balsam or balm, and so it is singular good against bruises, and bones broken, or out of joint, and giveth much ease to the cholic and splenetic diseases; as also for ruptures or burstings. 

The decoction of the root in white wine, provokes urine exceedingly, and cleanseth the bladder and passages of urine.”

  Modern day science recognizes that the Royal fern has antispasmodic, antioxidant, antibacterial and astringent properties. In the International Journal of Pharmaceutical and Biological Archives, 2011, vol.2 (1) pp559-62, “Preliminary Antibacterial and Phytochemical Assessment of Osmunda regalis L.” Toji Thomas concludes:-

 “Leaves can be recommended as a source for isolating and characterizing new antibacterial drugs for modern medicine.”

  It seems that those ancient ferns will have a productive modern use.
