Nature cures nature: Hypericum perforatum attenuates physical withdrawal signs in opium dependent rats.

CONTEXT: Hypericum perforatum Linn. (Hypericaceae) (St. John's wort) attenuates opium withdrawal signs. AIM: To explore the therapeutic potential of Hypericum perforatum in the management of opium-induced withdrawal syndrome. MATERIALS AND METHODS: The effect of the Hypericum perforatum hydro-ethanol extract was investigated for potential to reverse naloxone (0.25 mg/kg)-induced opium withdrawal physical signs. Rats received opium extract (80-650 mg/kg) twice daily for 8 days along with Hypericum perforatum (20 mg/kg, orally) twice daily in chronic treatment and the same single dose 1 h before induction of withdrawal syndrome in the acute treated group. RESULTS: Hypericum perforatum reduced stereotype jumps and wet dog shake number in the chronic treatment compared to the saline control group (F(2, 24) = 3.968, p < 0. 05) and (F(2, 24) = 3.689, p < 0.05), respectively. The plant extract in the acutely treated group reduced diarrhea (F(2, 24) = 4.850, p < 0. 05 vs. saline). It decreased rectal temperature by chronic treatment at 30 min (F(2, 24) = 4.88, p < 0.05), 60 min (F(2, 240 = 5.364, p < 0.01) and 120 min (F(2, 24) = 4.907, p < 0.05). DISCUSSION AND CONCLUSION: This study reveals that the extract of Hypericum perforatum attenuates some physical signs of opium withdrawal syndrome possibly through direct or indirect interaction with opioid receptors. Further study is needed to clarify its mechanism.

A homeopathic remedy from arnica, marigold, St. John's wort and comfrey accelerates in vitro wound scratch closure of NIH 3T3 fibroblasts.

BACKGROUND: Drugs of plant origin such as Arnica montana, Calendula officinalis or Hypericum perforatum have been frequently used to promote wound healing. While their effect on wound healing using preparations at pharmacological concentrations was supported by several in vitro and clinical studies, investigations of herbal homeopathic remedies on wound healing process are rare. The objective of this study was to investigate the effect of a commercial low potency homeopathic remedy Similasan® Arnica plus Spray on wound closure in a controlled, blind trial in vitro. METHODS: We investigated the effect of an ethanolic preparation composed of equal parts of Arnica montana 4x, Calendula officinalis 4x, Hypericum perforatum 4x and Symphytum officinale 6x (0712-2), its succussed hydroalcoholic solvent (0712-1) and unsuccussed solvent (0712-3) on NIH 3T3 fibroblasts. Cell viability was determined by WST-1 assay, cell growth using BrdU uptake, cell migration by chemotaxis assay and wound closure by CytoSelect ™Wound Healing Assay Kit which generated a defined "wound field". All assays were performed in three independent controlled experiments. RESULTS: None of the three substances affected cell viability and none showed a stimulating effect on cell proliferation. Preparation (0712-2) exerted a stimulating effect on fibroblast migration (31.9%) vs 14.7% with succussed solvent (0712-1) at 1:100 dilutions (p < 0.001). Unsuccussed solvent (0712-3) had no influence on cell migration (6.3%; p > 0.05). Preparation (0712-2) at a dilution of 1:100 promoted in vitro wound closure by 59.5% and differed significantly (p < 0.001) from succussed solvent (0712-1), which caused 22.1% wound closure. CONCLUSION: Results of this study showed that the low potency homeopathic remedy (0712-2) exerted in vitro wound closure potential in NIH 3T3 fibroblasts. This effect resulted from stimulation of fibroblasts motility rather than of their mitosis.

Hypericum perforatum to improve post-operative Pain Outcome after monosegmental Spinal microdiscectomy (HYPOS): a study protocol for a randomised, double-blind, placebo-controlled trial.

BACKGROUND: Spinal disc herniation is a frequently occurring degenerative disease of the spine. Many patients undergoing surgery suffer from radicular pain, known as memory pain, beginning from the third post-operative day. This results in the prescription of high-dose opioid medications. In homeopathy, Hypericum perforatum is known as a remedy for unbearable, shooting or jabbing pain especially when neural damage is involved. Reduction of pain after application of H. perforatum has been observed in previous studies. This study is aimed to investigate whether homeopathic H. perforatum in a potentisation of C200 leads to the reduction of post-operative pain and a decrease of pain medication compared to placebo. METHODS/DESIGN: This is a monocentric, double-blind, randomised placebo-controlled trial conducted at the Department of Neurosurgery at the Community Hospital Herdecke, Germany. One hundred study participants are being recruited from inpatients undergoing elective, monosegmental, lumbar microdiscectomy surgery. Patients are randomly allocated to receive homeopathic treatment or placebo in addition to usual pain management after surgery. The primary clinical outcome is pain reduction after 3 days of inpatient care as measured by pain reduction of subjective pain on a 100-mm Visual Analogue Scale (VAS) at the third post-operative day. Statistical analysis will be carried out by means of a covariance model with adjustment for baseline values and patient expectation for all randomised patients. DISCUSSION: This study is the first trial of classical homeopathy that will evaluate the efficacy of homeopathic H. perforatum after monosegmental spinal microdiscectomy. We intend to clarify the potential of homoeopathic H. perforatum to reduce surgery-associated pain. TRIAL REGISTRATION: German Clinical Trials Register, ID: DRKS00007913 .

Hypericum perforatum (St. John's Wort) as a possible therapeutic alternative for the management of trigeminal neuralgia (TN) - A case report.

Hypericum perforatum (St. John's Wort) is an alternative remedy used primarily for depression but also is used for rheumatism, gastroenteritis, headache and neuralgias. The mechanism of action of Hypericum perforatum comprehends a neurotransmitter inhibitory profile, and potential anti-inflammatory and anti-oxidant effects suggesting a role for pain management. In this case report, we describe a 53-year-old Hispanic female patient who came to our orofacial pain clinical service presenting with a history of trigeminal neuralgia (TN). The patient was not able to get an appointment soon enough and decided to take an over the counter homeopathic preparation of Hypericum perforatum since she found on the internet that it was effective for nerve pain. The patient responded dramatically to the Hypericum perforatum preparation. The use of this homeopathic preparation relieved completely the TN pain. The management of TN is often a challenge. Hypericum perforatum may be a promising therapeutic option for TN that deserves to be explored further to solidly support its use in the clinical setting.
