Sönmez DZ, Taşcı S. The Effect of St. John's Wort Oil (Hypericum Perforatum L.) in Knee Osteoarthritis: A Randomized Controlled and Qualitative Study. Pain Manag Nurs 2024; 25:e115-e125. [PMID: 38242739 DOI: 10.1016/j.pmn.2023.12.002] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/22/2023] [Revised: 11/07/2023] [Accepted: 12/10/2023] [Indexed: 01/21/2024]
Abstract
BACKGROUND Reducing pain and improving physical function are critical in the treatment of osteoarthritis. Although individuals use St. John's Wort oil to relieve pain due to osteoarthritis, no scientific research has been found investigating its effectiveness. AIM This study investigated the effect of St. John's Wort oil on pain intensity and physical functions in people with knee osteoarthritis. METHODS This study adopted a single-blind, randomized, placebo-controlled, and qualitative mixed design. The sample consisted of 60 patients randomized into intervention (n = 30) and placebo control (n=30) groups. The experimental group participants were treated with topically St. John's Wort oil three times a week for 3 weeks, and the placebo control group participants were treated with olive oil three times a week for 3 weeks. Quantitative data were collected using a patient identification form, the Western Ontario and McMaster Universities Osteoarthritis Index (WOMAC), and the Visual Analogue Scale. Qualitative data were collected through semi-structured interviews. RESULTS The experimental group had a significantly lower mean Visual Analog Scale score in the first, third, and fourth follow-ups than the control group. The experimental group had significantly lower mean WOMAC-pain, WOMAC-stiffness, and WOMAC-physical function subscale scores in the last follow-up than in the first follow-up. The qualitative data agreed with the quantitative data. CONCLUSIONS The results show that St. John's Wort oil helps people with knee osteoarthritis feel less pain and become physically more active. Additional research is warranted to better understand the effect of St. John's Wort oil on pain intensity and physical functions in people with knee osteoarthritis.

Hypericin as a promising natural bioactive naphthodianthrone: A review of its pharmacology, pharmacokinetics, toxicity, and safety. Phytother Res 2023; 37:5639-5656. [PMID: 37690821 DOI: 10.1002/ptr.8011] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/24/2023] [Revised: 08/28/2023] [Accepted: 08/29/2023] [Indexed: 09/12/2023]
Abstract
Hypericin can be derived from St. John's wort, which is widely spread around the world. As a natural product, it has been put into clinical practice such as wound healing and depression for a long time. In this article, we review the pharmacology, pharmacokinetics, and safety of hypericin, aiming to introduce the research advances and provide a full evaluation of it. Turns out hypericin, as a natural photosensitizer, exhibits an excellent capacity for anticancer, neuroprotection, and elimination of microorganisms, especially when activated by light, potent anticancer and antimicrobial effects are obtained after photodynamic therapy. The mechanisms of its therapeutic effects involve the induction of cell death, inhibition of cell cycle progression, inhibition of the reuptake of amines, and inhibition of virus replication. The pharmacokinetics properties indicate that hypericin has poor water solubility and bioavailability. The distribution and excretion are fast, and it is metabolized in bile. The toxicity of hypericin is rarely reported and the conventional use of it rarely causes adverse effects except for photosensitization. Therefore, we may conclude that hypericin can be used safely and effectively against a variety of diseases. We hope to provide researchers with detailed guidance and enlighten the development of it.

Abstract
Neuropathic pain affects 7-10% of the population and is often ineffectively and incompletely treated. Although the gold standard for treatment of neuropathic pain includes tricyclic antidepressants (TCAs), serotonin-noradrenaline reuptake inhibitors, and anticonvulsants, patients suffering from neuropathic pain are increasingly turning to nonpharmacologic treatments, including nutritional supplements for analgesia. So-called "nutraceuticals" have garnered significant interest among patients seeking to self-treat their neuropathic pain with readily available supplements. The supplements most often used by patients include vitamins such as vitamin B and vitamin D, trace minerals zinc and magnesium, and herbal remedies such as curcumin and St. John's Wort. However, evidence surrounding the efficacy and mechanisms of these supplements in neuropathic pain is limited, and the scientific literature consists primarily of preclinical animal models, case studies, and small randomized controlled trials (RCTs). Further exploration into large randomized controlled trials is needed to fully inform patients and physicians on the utility of these supplements in neuropathic pain. In this review, we explore the basis behind using several nutritional supplements commonly used by patients with neuropathic pain seen in rheumatology clinics.

Abstract
Complementary and alternative medicines such as herbal medicines are not currently part of the conventional medical system. As the popularity of and global market for herbal medicine grows among all age groups, with supporting scientific data and clinical trials, specific alternative treatments such as herbal medicine can be reclassified as a practice of conventional medicine. One of the most common conditions for which adults use herbal medicine is pain. However, herbal medicines carry safety concerns and may impact the efficacy of conventional therapies. Unfortunately, mechanisms of action are poorly understood, and their use is unregulated and often underreported to medical professionals. This review aims to compile common and available herbal medicines which can be used as an alternative to or in combination with conventional pain management approaches. Efficacy and safety are assessed through clinical studies on pain relief. Ensuing herb–drug interactions such as cytochrome modulation, additive and synergistic effects, and contraindications are discussed. While self-management has been recognized as part of the overall treatment strategy for patients suffering from chronic pain, it is important for practitioners to be able to also optimize and integrate herbal medicine and, if warranted, other complementary and alternative medicines into their care.

Abstract
The interaction between neurons and glia is pivotal for the development of chronic opioid tolerance. One of the most important mechanisms of cell-to-cell interaction is the Notch signaling pathway. In this chapter we propose a double-immunofluorescence method to observe and quantify the colocalization of Notch-1 and mu-opioid receptor (MOR-1), using both neuronal and astrocyte markers.

Abstract
Purpose Postoperative pain is a common clinical problem. In this study, we aimed to investigate the role of protein kinase C βII (PKCβII) in the progression of postoperative pain following skin/muscle incision and retraction (SMIR) surgery. Materials and methods SMIR postoperative pain model was established in rats, akin to a clinical procedure. The expression level and location of p-PKCβII were observed in dorsal root ganglion (DRG) or spinal cord from SMIR-operated rats by Western blotting and immunofluorescence. In addition, the effects of PKCβII on the expression of protein gene product 9.5 (PGP9.5) or vascular endothelial growth factor (VEGF) were assessed by using pharmacological activator and inhibitor of PKCβII. Moreover, mechanical withdrawal threshold (MWT) was assessed before or after SMIR-operated rats were treated with inhibitor or activator of PKCβII. Results The expression of PKCβII in DRG and spinal cord was significantly increased after SMIR surgery (P < 0.001, P < 0.01) and expression of PKCβII was located in the neurons of the spinal cord, and magnocellular neurons, non-peptide neurons, and peptide neurons in DRG. Besides, compared with skin/muscle incision group, retraction caused a marked increase in the expression of PKCβII and a significant decrease of MWT (P < 0.001, P < 0.05). The activator of PKCβII greatly increased the expression of PGP9.5 and VEGF (P < 0.05, P < 0.01) and enhanced MWT (P < 0.001), while inhibitor of PKCβII decreased the expression of PGP9.5 and VEGF and attenuated MWT (P < 0.05, P < 0.01, P < 0.001). Conclusion Activation of PKCβII signaling pathways might be an important mechanism in the progression of postoperative pain.

Abstract
Objective In this study, we compared the efficacy of a combination of PKC-blocker St. John's Wort (SJW) and morphine in mice with painful antiretroviral (2,3-dideoxycitidine [ddC]) and chemotherapic (oxaliplatin) neuropathy. Methods Morphine (1 and 5 mg/Kg i.p.), SJW (1 and 5 mg/Kg o.s.), or their combination was administered by systemic injection, and antinociception was determined by using the hot and cold plate tests. Results Here we demonstrate the ability of SJW to relieve neuropathic pain in mice neuropathic models and a potentiation of morphine antinociception in thermal pain. The potentiating effect shown by SJW was not secondary to its antinociceptive activity as the increase of the morphine antinociceptive effect was produced at a dose (1mg/kg o.s.) devoid of any capability to modulate the pain threshold in neuropathic pain mice. Further examinations of the SJW main components revealed that hypericin was responsible for the potentiating properties whereas flavonoids were ineffective. Conclusions These results show that SJW has notable antinociceptive activity for both neuropathic pain models and could be used in neuropathic pain relief alone or in combination with morphine. These data support the utility of combination SJW/opioid therapy in pain management for antinociceptive efficacy by enhancing opioid analgesia.

Abstract
Abstract
Objectives
This study was conducted to explore whether Hypericum perforatum L. (HPL) as a potent antioxidant protects against oxidative stress, cytokine production and caspase expression in muscle (soleus), brain and blood of sciatic nerve injury (SNI)-induced rats.
Methods
Thirty-five rats were equally divided into five groups. The first and second were used as untreated control and sham control groups, respectively. The third, fourth and fifth were sham + HPL, SNI and SNI + HPL groups, respectively. The third and fifth groups received 30 mg/kg HPL via gastric gavage for 28 days.
Key findings
High levels of muscle, brain and red blood cell (RBC) lipid peroxidation, plasma cytokine (TNF-α, IL-1β and IL-2), muscle PARP, caspase 3 and 9 expression levels were decreased by HPL treatments. Plasma glutathione peroxidase (GPx) activity, α-tocopherol and melatonin, muscle, brain and RBC reduced glutathione (GSH) concentrations were decreased by SNI induction, whereas their values were increased by HPL treatments. β-carotene and retinol concentrations did not change in the five groups.
Conclusion
HPL may play a role in preventing SNI-induced inflammatory, oxidative and apoptotic blood, muscle and brain damages through upregulation of the GSH and GPx values but downregulation of PARP, caspase level and cytokine production in SNI-induced rats.

Abstract
ETHNOPHARMACOLOGICAL RELEVANCE Hypericum perforatum L. (Hypericaceae), popularly called St. John's wort (SJW), has a rich historical background being one of the oldest used and most extensively investigated medicinal herbs. Many bioactivities and applications of SJW are listed in popular and in scientific literature, including antibacterial, antiviral, anti-inflammatory. In the last three decades many studies focused on the antidepressant activity of SJW extracts. However, several studies in recent years also described the antinociceptive and analgesic properties of SJW that validate the traditional uses of the plant in pain conditions. AIM OF THE REVIEW This review provides up-to-date information on the traditional uses, pre-clinical and clinical evidence on the pain relieving activity of SJW and its active ingredients, and focuses on the possible exploitation of this plant for the management of pain. MATERIALS AND METHODS Historical ethnobotanical publications from 1597 were reviewed for finding local and traditional uses. The relevant data on the preclinical and clinical effects of SJW were searched using various databases such as PubMed, Science Direct, Scopus, and Google Scholar. Plant taxonomy was validated by the database Plantlist.org. RESULTS Preclinical animal studies demonstrated the ability of low doses of SJW dry extracts (0.3% hypericins; 3-5% hyperforins) to induce antinociception, to relieve from acute and chronic hyperalgesic states and to augment opioid analgesia. Clinical studies (homeopathic remedies, dry extracts) highlighted dental pain conditions as a promising SJW application. In vivo and in vitro studies showed that the main components responsible for the pain relieving activity are hyperforin and hypericin. SJW analgesia appears at low doses (5-100mg/kg), minimizing the risk of herbal-drug interactions produced by hyperforin, a potent inducer of CYP enzymes. CONCLUSION Preclinical studies indicate a potential use of SJW in medical pain management. However, clinical research in this field is still scarce and the few studies available on chronic pain produced negative results. Prospective randomized controlled clinical trials performed at low doses are needed to validate its potential efficacy in humans.

Abstract
This paper is the thirty-eighth consecutive installment of the annual review of research concerning the endogenous opioid system. It summarizes papers published during 2015 that studied the behavioral effects of molecular, pharmacological and genetic manipulation of opioid peptides, opioid receptors, opioid agonists and opioid antagonists. The particular topics that continue to be covered include the molecular-biochemical effects and neurochemical localization studies of endogenous opioids and their receptors related to behavior, and the roles of these opioid peptides and receptors in pain and analgesia, stress and social status, tolerance and dependence, learning and memory, eating and drinking, drug abuse and alcohol, sexual activity and hormones, pregnancy, development and endocrinology, mental illness and mood, seizures and neurologic disorders, electrical-related activity and neurophysiology, general activity and locomotion, gastrointestinal, renal and hepatic functions, cardiovascular responses, respiration and thermoregulation, and immunological responses.
