  • St John's wort refers to the species Hypericum perforatum, also known as Tipton's Weed or Klamath weed, but, with qualifiers, is used to refer to any species of the genus Hypericum. Therefore, H. perforatum is sometimes called Common St. John's wort to differentiate it.
  • St. Johnís Wort has been used in folk medicine since the Middle Ages. It was used by mouth to reduce inflammation, to ease stomach pain, to help sleeplessness, as  a diuretic, to ease nerve pain, for headaches, and to treat anxiety. It was applied to the skin to treat bruises, muscle pain, mild
    burns, smooth white spots on the skin, and for hemorrhoids. Recently, St. Johnís Wort has been used to treat mild depression.
  • Pressurized solvent extraction is a new technique that reduces solvent consumption and sample preparation time.The fast PSE is an automated system which processes six samples simultaneously. The parallel processing technology of the fast PSE dramatically increases sample throughput compared to Soxhlet and pressurized solvent extraction systems that employ serial processing. In addition to rapid extraction times, significant reduction in solvent consumption is achieved.
  • The extracts of St. Johnīs wort Hypericum perforatum L .ssp. angustifolium from the new locality, Sobina, (the surroundings of Vranje, South Serbia, Yugoslavia) obtained by high pressure extraction with CO2, exert antimicrobial action, where the extract obtained under higher pressure exerted stronger action
  • St. Johnswort (Hypericum perforatum L.) isutilized as a bulk raw material by the herbal products industry, where fresh flowers and flowering tips are manufactured into dried extract.
  • The market for Saint Johnís Wort varies with world demand and production. Saint Johnís Wort cameinto the limelight in 1997 when it was featured onthe television program 20/20. The commercial cropin Europe was less than projected and the resulting effect was that prices soared to the $20.00/lb. (US)level within one week. Saint Johnís Wort continuesto be an important herb in the North American andEuropean medicinal markets but prices swings aremuch less than in 1997. Prices in 1999 varied from $5.00-13.00/US/lb. for small lots and were as low as$1.50/lb. US for large lots. It is imperative thatthorough market research be carried out and potentialbuyers be located and communicated with prior toharvesting this crop.
  • In modern medicine, standardized Hypericum extract (obtained from H. perforatum) is commonly used as a treatment for depression and anxiety disorders
  • The active therapeutic ingredients in St. John's wort are hypericin, pseudohypericin and xanthones, although other components may support the action of these compounds. St. John's wort extract preparations are standardized to 0.3 percent hypericin. The typical adult dosage is 300 milligrams taken three times a day, and that means that a person taking St. John's wort gets 2.7 milligrams of hypericin a day.
  • Traditionally, extracts of St. Johns Wort (which contain hypericin) have been used as an antidepressant, possibly by acting as a MAO inhibitor. The psychotropic effects attributed to hypericin in St. Johns Wort extract suggest that the pigment compound can cross the blood brain barrier
  • In accordance with the legend of wound healing during the Crusades, we find agreement in modern times. St. Johns Wort today has been found to be very beneficial in healing wounds and is especially good for dirty, septic wounds. St. Johns Wort has been used in case of putrid leg ulcers, that noting heals. Like the leach that was used not too many years ago for wound cleansing it does not destroy the healthy tissues and healthy cells but it cleans the dirt out of septic wounds.
