Adults: Topical formulations generally recommend application to the affected area, with specific dosing instructions provided by the product label. For oral supplements, follow the manufacturer's guidelines or consult a healthcare professional.

Mechanism of action

Capsaicin, the main active component in Capsicum, exerts its effects by binding to the TRPV1 (transient receptor potential vanilloid 1) receptor, which is a cation channel involved in the transmission of pain and heat sensations. This binding leads to the depolarization of sensory neurons, resulting in the release of substance P, a neuropeptide associated with pain signaling. Continuous exposure to capsaicin results in the desensitization of these receptors, leading to decreased pain perception over time.

Pharmacodynamics

The analgesic properties of Capsicum are attributed to its ability to alter the perception of pain. Capsaicin induces a sensation of warmth and pain initially, which is followed by a prolonged analgesic effect due to the depletion of substance P from the nerve endings. Additionally, Capsicum may exhibit anti-inflammatory effects through the modulation of cytokine release and inhibition of inflammatory pathways, contributing to its therapeutic applications in pain management and inflammatory conditions.

Pharmacokinetics

Capsaicin is poorly absorbed when ingested orally, but it can be effectively absorbed through the skin when applied topically. After application, it is metabolized by the liver, and its metabolites are excreted primarily through the kidneys. The onset of action for topical preparations can vary, with effects often observed within hours. The duration of action may last from several hours to days, depending on the formulation and the area of application.

Adverse effects

Adults: Refer to specific product guidelines or consult a healthcare professional for appropriate dosing of eucalyptus oil, as it varies based on formulation and indication.

Mechanism of action

Eucalyptus oil contains compounds such as eucalyptol (1,8-cineole) that exhibit antimicrobial properties. It acts on the respiratory system by promoting bronchodilation and reducing mucus production. The oil also has a cooling effect, which can provide relief from symptoms of respiratory distress. Additionally, the oil's anti-inflammatory properties help decrease inflammation in the airways.

Pharmacodynamics

The primary active ingredient in eucalyptus oil, eucalyptol, interacts with the body's inflammatory response and can modulate the activity of neurotransmitters involved in pain signaling. It may enhance mucociliary clearance in the respiratory tract, facilitating the expulsion of mucus and pathogens. The analgesic effects can help relieve discomfort associated with respiratory infections.

Pharmacokinetics

Eucalyptus oil is typically administered via inhalation or topical application. When inhaled, components like eucalyptol are absorbed through the mucous membranes of the respiratory tract and rapidly distributed throughout the body. The oil is metabolized primarily in the liver, and its metabolites are excreted in urine. The half-life of eucalyptol varies but is generally short, necessitating frequent dosing for sustained effects.

Breast-feeding

Caution is advised when using eucalyptus during breastfeeding, as it may pass into breast milk and could affect the infant.

Storage

Store in a cool, dry place away from direct sunlight. Keep out of reach of children.

Formulations

• Eucalyptus oil (topical, inhalation, or oral preparations)
• Eucalyptus leaves (dried for teas or extracts)

Indications

• Adrenal insufficiency
• Chronic inflammatory conditions

Mechanism of action

Glycyrrhizin, the primary active component of Glycyrrhiza, exerts its effects primarily through inhibition of the enzyme 11β-hydroxysteroid dehydrogenase type 2 (11β-HSD2). This inhibition prevents the conversion of active cortisol to inactive cortisone, leading to increased cortisol levels. Elevated cortisol mimics the effects of aldosterone, resulting in sodium retention, potassium excretion, and increased blood pressure. Additionally, licorice has anti-inflammatory and antiviral properties attributed to its ability to modulate various immune pathways and inhibit viral replication.

Pharmacodynamics

The pharmacodynamic effects of Glycyrrhiza include anti-inflammatory, antiviral, and immunomodulatory activities. Glycyrrhizin has been shown to reduce inflammation by inhibiting the production of pro-inflammatory cytokines and mediators. Its potential antiviral properties are particularly noted in viral infections such as hepatitis C and COVID-19, where it may inhibit viral replication. Furthermore, its ability to enhance the effects of corticosteroids can be beneficial in treating conditions associated with adrenal insufficiency or chronic inflammation.

Pharmacokinetics

Glycyrrhizin is absorbed from the gastrointestinal tract, with peak plasma concentrations occurring within 1-2 hours after oral administration. It undergoes extensive metabolism in the liver, primarily through conjugation processes, leading to the formation of glycyrrhetic acid as a major metabolite. The elimination half-life of glycyrrhizin is approximately 6-8 hours. Glycyrrhiza components are excreted in urine predominantly as conjugated forms. Long-term use can lead to accumulation and potential side effects due to its mineralocorticoid-like effects.

Contra-indications

Mechanism of action

Menthol acts as an agonist for the transient receptor potential subtype M8 (TRPM8), a non-selective cation channel that is activated by cold temperatures. This activation leads to calcium influx in mast cells, inducing the release of histamine, which can trigger allergic responses such as urticaria, asthma, and rhinitis. Menthol's ability to induce histamine release via TRPM8 suggests potential therapeutic applications for TRPM8 antagonists in managing cold- and menthol-induced allergies.

Pharmacodynamics

Menthol produces a cooling effect by stimulating sensory neurons that convey cold sensations. It interacts with TRPM8 channels, leading to the activation of intracellular signaling pathways that can result in vasodilation and increased blood flow to the area of application. This cooling sensation can provide symptomatic relief in conditions characterized by pain or irritation.

Pharmacokinetics

Menthol is absorbed through the skin and mucous membranes, with systemic effects depending on the route of administration. Its bioavailability can vary, and it is metabolized primarily in the liver. The elimination half-life and excretion pathways have not been extensively characterized, but menthol is generally considered to have a rapid onset of action with effects lasting for a few hours.

Adverse effects

• Allergic reactions
• Urticaria
• Asthma
• Rhinitis
• Skin irritation

Precautions

• Use with caution in patients with known allergies to menthol or related compounds
• May exacerbate asthma in sensitive individuals

Pregnancy

There are no well-controlled studies of menthol in pregnant women. Menthol should be used during pregnancy only if clearly needed.

Breast-feeding

Mechanism of action

The active compounds in pine bark extract, particularly proanthocyanidins, exert their effects through several mechanisms. They enhance nitric oxide production, which leads to vasodilation and improved blood flow. Additionally, they inhibit the oxidation of low-density lipoprotein (LDL) cholesterol, thus contributing to cardiovascular health. The antioxidant properties help reduce oxidative stress and inflammation by scavenging free radicals and modulating inflammatory pathways.

Pharmacodynamics

Pine bark extract displays a range of pharmacodynamic effects, including vasodilatory, anti-inflammatory, and antioxidant properties. These effects can lead to improved circulation, reduced symptoms of chronic venous insufficiency, and potential benefits in conditions associated with oxidative stress. The anti-inflammatory effects may also contribute to pain relief in osteoarthritis and other inflammatory conditions.

Pharmacokinetics

The pharmacokinetics of pine bark extract are influenced by its route of administration, typically oral. After ingestion, proanthocyanidins are absorbed in the gastrointestinal tract and distributed throughout the body. They undergo metabolic conversion in the liver, with a half-life that can vary based on individual metabolism and formulation. Elimination occurs primarily through urine, with metabolites detectable for several hours post-administration.

Breast-feeding

It is not known whether pumilio is excreted in human milk. Caution should be exercised when administering to breastfeeding mothers.

Storage

Store in a cool, dry place, away from direct sunlight. Keep out of reach of children.

Mechanism of action

Exposure to low temperatures often causes allergic responses or urticaria. Similarly, menthol, a common food additive is also known to cause urticaria, asthma, and rhinitis. However, despite the obvious clinical implications, the molecular mechanisms responsible for inducing allergic responses to low temperatures and menthol have not been determined. Because a non-selective cation channel, transient receptor potential subtype M8 (TRPM8) is activated by cold and menthol, we hypothesized that this channel mediates cold- and menthol-induced histamine release in mast cells. Here, we report that TRPM8 is expressed in the basophilic leukemia mast cell line, RBL-2H3, and that exposure to menthol or low temperatures induced Ca(2+) influx in RBL-2H3 cells, which was reversed by a TRPM8 blocker. Furthermore, menthol, a TRPM8 agonist, induced the dose-dependent release of histamine from RBL-2H3 cells. When TRPM8 transcripts were reduced by siRNA (small interfering RNA), menthol- and cold-induced Ca(2+) influx and histamine release were significantly reduced. In addition, subcutaneous injection of menthol evoked scratching, a typical histamine-induced response which was reversed by a TRPM8 blocker. Thus, our findings indicate that TRPM8 mediates the menthol- and cold-induced allergic responses of mast cells, and suggest that TRPM8 antagonists be viewed as potential treatments for cold- and menthol-induced allergies. /DL-Menthol/ Menthol's characteristic cooling sensation is due, in part, to the activation of sensory neurons generally termed transient receptor potential (TRP) channels, in particular transient receptor potential melastatin family member 8 (TRPM8) and transient receptor potential subfamily A, member 1 (TRPA1). Menthol acts upon TRPM8 receptors by rapidly increasing intracellular calcium and mobilizing calcium flux through the channels to induce cold response signals at the application site. Aside from its cold-inducing sensation capabilities, menthol exhibits cytotoxic effects in cancer cells, induces reduction in malignant cell growth, and engages in synergistic excitation of GABA receptors and sodium ion channels resulting in analgesia. /DL-Menthol/ In recent years, the transient receptor potential melastatin member 8 (TRPM8) channel has emerged as a promising prognostic marker and putative therapeutic target in prostate cancer. We have found that forced overexpression of TRPM8 in PC-3 cells can inhibit the cell proliferation and motility probably through the TRPM8 activation. In this study, we aimed to investigate whether activating the TRPM8 channel by its selective agonist menthol can inhibit the proliferation and motility of androgen-independent prostate cancer (AIPC) with remarkable expression of TRPM8. Menthol is a naturally occurring compound, which has been widely used in cosmetics and pharmaceutical products, and also as flavoring in food. DU145 cells are androgen-independent but have a remarkable expression of TRPM8. The demonstration of the existence of TRPM8 and the absence of TRPA1 in DU145 cells provided the foundation for the following experiments, because both TRPM8 and TRPA1 are molecular targets of menthol. The outcome of MTT assay indicated that menthol inhibited the cell growth (p < 0.01). Cell cycle distribution and scratch assay analysis revealed that menthol induced cell cycle arrest at the G(0)/G(1) phase (p < 0.01). Furthermore, menthol inhibited the migration of DU145 cells by downregulating the focal-adhesion kinase. So it suggests that the activation of the existing TRPM8 channels may serve as a potential and pragmatic treatment for those AIPC with remarkable expression of TRPM8, and menthol is a useful compound for future development as an anticancer agent. /DL-Menthol/
