.St John's wort (traditionally pronounced /seɪntˈdʒɒnz ˈwɜrt/, now sometimes the spelling pronunciation /ˈwɔrt/)[1] is the plant 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.^ Amethyst Botanical name : Hypericum perforatum St John's wort is a perennial plant with extensive, creeping rhizomes.

^ Before you try medication, I suggest trying a regimen of St. John's Wort for a while (whatever the dosage is on the bottle -- usually 2 capsules 3 times per day).

The species of Hypericum have been placed by some in the family Hypericaceae, but more recently have been included in the Clusiaceae.[2] Approximately 370 species of the genus Hypericum exist worldwide with a native geographical distribution including temperate and subtropical regions of North America, Europe, Asia Minor, Russia, India, and China.
St. John's wort is widely known as a herbal treatment for depression.

The plant

.Hypericum perforatum is a yellow-flowering, stoloniferous or sarmentose, perennial herb indigenous to Europe, which has been introduced to many temperate areas of the world and grows wild in many meadows.^ Amethyst Botanical name : Hypericum perforatum St John's wort is a perennial plant with extensive, creeping rhizomes.

.The common name comes from its traditional flowering and harvesting on St John's day, 24 June.^ Amethyst Botanical name : Hypericum perforatum St John's wort is a perennial plant with extensive, creeping rhizomes.

It thrives in areas with either a winter- or summer-dominant rainfall pattern; however, distribution is restricted by temperatures too low for seed germination or seedling survival. Altitudes greater than 1500 m, rainfall less than 500 mm, and a daily mean January temperature greater than 24 degrees C are considered limiting thresholds. .Depending on environmental and climatic conditions, and rosette age, St John’s wort will alter growth form and habit to promote survival.^ Amethyst Botanical name : Hypericum perforatum St John's wort is a perennial plant with extensive, creeping rhizomes.

Summer rains are particularly effective in allowing the plant to grow vegetatively, following defoliation by insects or grazing.
The seeds can persist for decades in the soil seed bank, germinating following disturbance.[3]

In some countries, such as Germany, it is commonly prescribed for mild depression, especially in children, adolescents, and where cost is a concern.[5] A report in the Cochrane Review states,
.The available evidence suggests that the hypericum extracts tested in the included trials a) are superior to placebo in patients with major depression; b) are similarly effective as standard antidepressants; and c) have fewer side effects than standard antidepressants.^ If you have more severe depression antidepressants are usually the first choice, since they're cheaper than and just as effective as CBT: you may get something like fluoxetine (Prozac) or citalopram.

.There are two issues which complicate the interpretation of our findings: 1) While the influence of precision on study results in placebo-controlled trials is less pronounced in this updated version of our review compared to the previous version (Linde 2005a), results from more precise trials still show smaller effects over placebo than less precise trials.^ But the number of these " whippings " was much less than in the previous century, even although we find an entry of no less than six women whipped on one occasion, one after the other, for immorality, so late as 1776 (see p.

Major depressive disorder

Seedlings of St John's wort
An analysis of twenty-nine clinical trials with more than five thousand patients was conducted by Cochrane Collaboration. The review concluded that extracts of St. John's wort were superior to placebo in patients with major depression. St. John's wort had similar efficacy to standard antidepressants. The rate of side effects was twice lower than for newer SSRI antidepressants and five times lower than for older tricyclic antidepressants.[6] However, this review also noted that studies more favourably supporting the effects of St. John's wort as an antidepressant, were predominantly from German-speaking countries. .The authors could not rule out the possibility that some smaller studies from those countries were flawed and reported overoptimistic results.^ Indeed all that we could spare from the Ladies, was spent In his study, or in sallying out to mid Roman Camps, Tumuli, etc.

.National Center for Complementary and Alternative Medicine (NCCAM) and other NIH-affiliated organizations hold that St John's wort has minimal or no effects beyond placebo in the treatment of major depression[7][8] This conclusion is based primarily on one trial with negative outcome conducted by NCCAM.[9] The authors of the study themselves, as well as several others, pointed out the low assay sensitivity of this study, and how only limited conclusions can be drawn from its results.^ Amethyst Botanical name : Hypericum perforatum St John's wort is a perennial plant with extensive, creeping rhizomes.

Other medical uses

St. John's wort is being studied for effectiveness in the treatment of certain somatoform disorders. .Results from the initial studies are mixed and still inconclusive; some research has found no effectiveness, other research has found a slight lightening of symptoms.^ In some of the farms and woods other parishes are mixed up.

Further study is needed and is being performed.
A constituent chemical, hyperforin, may be useful for treatment of alcoholism, although dosage, safety and efficacy have not been studied.[13] Hyperforin has also been found to have antibacterial properties against gram-negative bacteria, although dosage, safety and efficacy has not been studied.[14]
A randomized controlled trial of St. John's wort found no significant difference between it and placebo in the management of ADHD symptoms over eight weeks. However, the St. John's Wort extract used in the study, originally confirmed to contain 0.3% hypericin, was allowed to degrade to levels of 0.13% hypericin and 0.14% hyperforin. Given that the level of hyperforin was not ascertained at the beginning of the study, and levels of both hyperforin and hypericin were well below that used in other studies, little can be determined based on this study alone.[15]
A research team from the Universidad Complutense de Madrid (UCM) published a study entitled, “Hypericum perforatum. Possible option against Parkinson's disease”, which suggests that this plant with antidepressant properties has antioxidant active ingredients that could help reduce the neuronal degeneration caused by the disease.[16]

This can lead to visual sensitivity to light and to sunburns in situations that would not normally cause them.[17] Related to this, recent studies concluded that the extract reacts with light, both visible and ultraviolet, to produce free radicals, molecules that can damage the cells of the body. These can react with vital proteins in the eye which, if damaged, precipitate out causing cataracts.[19]

Pharmacokinetic interactions

.St John's wort has been shown to cause multiple drug interactions through induction of the cytochrome P450 enzyme CYP3A4, but also CYP2C9.^ Amethyst Botanical name : Hypericum perforatum St John's wort is a perennial plant with extensive, creeping rhizomes.

^ Customs included decking the house (especially over the front door) with birch, fennel, St. John's wort, orpine, and white lilies.

^ The flowers and stems of St John's wort have also been used to produce red and yellow dyes.

This results in the increased metabolism of those drugs, resulting in decreased concentration and clinical effect. The principal constituent thought to be responsible is hyperforin.
St. John's wort also has been shown to cause drug interactions through the induction of the P-glycoprotein (P-gp) efflux transporter. Increased P-gp expression results in decreased absorption and increased clearance of those drugs which leads to lower clinical concentrations and efficacy.[20]

History

The first recorded use of Hypericum for medicinal purposes dates back to ancient Greece, and it has been used ever since. Hypericum was also used by Native Americans internally as an abortifacient and externally as an anti-inflammatory, astringent, and antiseptic.
Its use as a herbal tea has long been enjoyed.
.The flowers and stems of St John's wort have also been used to produce red and yellow dyes.^ Thankyou to everyone for telling me it is a type of Hypericum , also known as Rose of Sharon , Star of St.John and St.John's Wort .
