Picroprotect Picrorhiza Kurroa Extract
Also known as: Katuki, Picrorhiza, Picrorhiza kurroa Royle ex Benth., Picrorhiza kurroa
Overview
*Picrorhiza kurroa* is a perennial herb from the Scrophulariaceae family, commonly found in the Himalayan regions. Traditionally utilized in Ayurvedic medicine, this plant possesses various pharmacological properties, including hepatoprotective, antioxidant, anti-inflammatory, anti-asthmatic, and anti-neoplastic activities. The primary bioactive compounds are iridoid glycosides (e.g., picroside-1 and kutkoside), along with alkaloids and phenolic compounds. Although extensive studies support its efficacy, there remains a scarcity of large-scale clinical trials, necessitating further investigation to substantiate its safety and therapeutic applications in humans.
Benefits
{"hepatoprotective_activity":{"description":"Significant liver protection against toxins such as ethanol, reducing damage markers (ALT and AST) by up to 70%.","evidence_strength":"High, based on multiple animal studies.","population_benefits":"Especially beneficial for individuals with liver diseases like fatty liver and hepatitis."},"antioxidant_activity":{"description":"Robust antioxidant capacity demonstrated through various assays.","evidence_strength":"Moderate, with promising in vitro data.","population_benefits":"May benefit those with oxidative stress-related conditions."},"anti-neoplastic_activity":{"description":"Induces apoptosis in specific cancer cell lines.","evidence_strength":"Moderate, requiring more clinical confirmation.","population_benefits":"Potential benefits for cancer patients."},"anti-inflammatory_activity":{"description":"Demonstrated anti-inflammatory effects in animal models.","evidence_strength":"Moderate.","population_benefits":"Could assist individuals with inflammatory disorders."},"anti-asthmatic_activity":{"description":"Inhibits bronchial obstruction in guinea pigs.","evidence_strength":"Preliminary findings.","population_benefits":"Potentially useful for asthma sufferers."}}
How it works
*Picrorhiza kurroa* exerts hepatoprotective effects through bioactive compounds, particularly iridoids that enhance liver cell regeneration and reduce oxidative stress. Its antioxidant activity involves free radical scavenging and reducing lipid peroxidation, while anti-inflammatory properties result from the inhibition of inflammatory pathways mediated by compounds in the plant. Interaction occurs with the liver, immune system, and respiratory systems, influencing various biological functions.
Side effects
{"overall_safety":"Generally safe at traditional doses, with limited data on long-term safety.","common":"Gastrointestinal disturbances such as nausea and diarrhea may occur in over 5% of users.","uncommon":"Allergic reactions and skin rashes reported in 1-5% of cases.","rare":"Severe allergies and hepatotoxicity have been noted but are less than 1% of occurrences.","drug_interactions":"Caution advised with liver-metabolized medications like anticoagulants.","contraindications":"Not recommended for pregnant and breastfeeding women due to insufficient data.","special_population_considerations":"Limited safety data in children and the elderly."}
Dosage
{"minimum_effective":"Ranges from 100-200 mg/kg in animal studies for hepatoprotection.","optimal_dosage":"Traditional doses vary from 1-3 grams of dried rhizome daily, with standardized extracts advised.","maximum_safe_dose":"No established maximum; exceeding 3 grams daily is not recommended.","timing":"May vary based on condition but often taken around potential toxin exposure.","form_specific":"Standardized extracts in capsules or tablets are advisable for consistency.","absorption":"Enhanced bioavailability may occur with food."}
