Hypericum (St. John's Wort)

Hypericum is a genus of about 450 species of trees, shrubs and herbs that occurs in all temperate part of the world but has only in species in southern South America and two species in Australia and New Zealand.

It is a perennial herbaceous plant with mature stems and branches that are smooth without hairs.

St. John’s Wort was first mentioned in Roman times by Pliny the Elder in the 1st century AD. Around the same times, Diascorides, a Roman army doctor born in Greece recommended the imbibition of St. John’s Wort with special liquids ‘to expel many choleric excrements’.

Hypericum belongs to the family Clusiaceae and shares with all or most of the other genera of that family opposite simple entire exstipulate leaves, the presence of glandular secretions, free petals, fascicles of stamens and seeds lacking endosperm.

Hypericum perforatum (devil’s scourage, goat weed, rosin rose, St. John’s Wort, Tipton weed, witch’s herb) contains the naphthodianthrones hypericin, and pseudohypericin, flavonoids, such as hyperoside, isoquercitin and rutin, and phloroglucinols, such as adhyperforin and hyperforin. It is effective in mild to moderate depression.

Chickweed

Chickweed is one of the most common weeds worldwide. It has been used since ancient times to treat external inflammatory conditions and is also consumed as a tasty and nutritious vegetable.

Chickweed or Stellaria media is a small herbaceous annual. Occasionally the plant can be found standing upright, but more often it is seen prostrated, rooting at stem nodes.

The newer leaves are normally stemless; mature leaves have petioles, are opposite and ovate in shape. Stellaria media is a common plant. Owing to its European origin, it can be found in lawns, gardens, fields and other moist and disturbed soils.

It can be mixed with a pot of stronger-flavored greens, adding the chickweed to the pot in the last minute or two of cooking.

Chickweed can be eaten raw in salads, served as cooked greens, juiced or infused as a tea. It has also been used as a mild laxative and diuretic substance. Chickweed contains moderate amounts of vitamin C and iron.

In traditional medicine, chickweed is used as a diuretic, cardioactvie, and anti-inflammatory agent and is applied externally to treat patients with wounds, rheumatism, arthritis, dermatitis and some other skin disease.

Chickweed essential oil has been found to contain several well-known contact allergens: borneol, menthol, linalool, 1,8-cineole, and other terpenes such as epoxy-dehydro-caryophyllene, monoterpene alcohol-ester and caryophyllene.

Herbs Containing Thymol or Carvacrol

Herbs Containing Thymol or Carvacrol
The establishment of aromatic profiles for members of this group is complicated by the considerable confusion over nomenclature. The botany of the plants in the family Labiatae, which are variously known as “thyme” of “origanum” is very involved; much of the misunderstanding is due to the fact that Spanish thyme is often origanum and vice versa and the term “marjoram” or the French word “marjolaine” is applied to several aromatic plants of different species. In commerce, the position is not improved as the essential oils from these various plants are often blended and offered under both names. However, there is now general agreement for the following nomenclature.

THYME
Thyme is Thymus vulgaris, L. or Thymus zygis, L. The essential oil from these plants has a total phenol content of 40 – 60% of which not less than 90% is crystallize thymol.

WILD THYME
Wild thyme is usually regarded as Thymus serpyllum, L. and is not widely available except in Russia.

ORIGANUM
Origanum is Thymus capitatus and some other species of Thymus or Origanum the essential oil of which contains 60 – 75% of total phenols consisting mainly of noncrystallizable carvacrol.

WILD MARJORAM
Wild marjoram is either Origanum vulgarae, L. or Thymus masticina, L.

SWEET MARJORAM
Sweet marjoram is Marjorana hortensis, the essential oil of which does not contain any phenols.

WHITE THYME OIL
White thyme oil is not a prime essential oil from a different plant but it is redistillation of red thyme oil of commerce.

Bay Laurel

Bay Laurel
Bay Laurel (Laurus nobilis, Lauracae) also known as Sweet Bay is a tree which is cultivated throughout Turkey, Israel, Russia, Italy and France although, increasingly, commercial crops of leaves is being exported from Greece and Mexico. A similar crop is found in China but the variety is different and the leaves contain an essential oil having a marked phenolics odor not unlike that of West Indian bay.

The leaves yield about 2% essential oil when steam distilled. The leaves are 6–12 cm long and 2–4 cm broad, with a characteristic finely serrated and wrinkled margin. It is dioecious, with male and female flowers on separate plants; each flower is pale yellow-green, about 1 cm diameter, borne in pairs together beside a leaf (Herb). The fruit is a small black berry about 1 cm long, containing a single seed.

Component of the essential oil
Alpha–pinene
cineole (45 – 50%)

Beta–phellandrene
1- linalool
1-alpha-terpineol
geraniol
euogenol
methyl eugenol
geranyl and eugenyl esters
