Detailed Modern Research on Rosehip (Rosa canina L. and related spp.) Extract

1. Chemical Components:
   Rosehip is a nutrient-dense botanical with a complex profile:

• Vitamin C: Exceptionally high content, but varies significantly with species, processing, and extraction method.
• Carotenoids & Phenolic Compounds: Lycopene, beta-carotene, zeaxanthin, and various flavonoids (quercetin, catechin) and phenolic acids (gallic acid) are primary antioxidants.
• Galactolipids (GOPOs): Unique lipids, notably trans-tiliroside and the mono- and di-galactosyl glycerides (e.g., (2S)-1,2-di-O-[(9Z,12Z,15Z)-octadeca-9,12,15-trienoyl]-3-O-β-D-galactopyranosyl glycerol), considered key anti-inflammatory agents.
• Pectin & Dietary Fiber: High in soluble fiber, contributing to gut health and glycemic control.
• Essential Fatty Acids: Linoleic (omega-6) and alpha-linolenic (omega-3) acids present in the seed oil.

1. Documented Health Benefits (Pharmacological Actions):

• Anti-Inflammatory & Osteoarticular Health: Most robust evidence supports its use in osteoarthritis (OA) and rheumatoid arthritis (RA). Meta-analyses confirm GOPOs significantly reduce pain, stiffness, and improve joint mobility, likely by inhibiting chemotaxis of leukocytes and COX enzymes.
• Antioxidant Activity: High levels of Vitamin C and phenolics effectively scavenge free radicals, reduce oxidative stress markers (MDA), and boost endogenous antioxidant defenses (SOD, GPx).
• Skin Health: Topical and oral application promotes skin regeneration, reduces wrinkles, and protects against UV-induced photoaging. Vitamin C is critical for collagen synthesis, while seed oil (rich in EFAs) improves skin barrier function and hydration.
• Metabolic & Cardiovascular Health: Shows anti-obesity potential by inhibiting pancreatic lipase and adipogenesis; improves lipid profiles and glucose metabolism in preclinical models, linked to PPAR-γ activation.
• Antimicrobial & Gut Health: Exhibits inhibitory effects against H. pylori and other pathogens. Pectin acts as a prebiotic, supporting beneficial gut microbiota.

III. Interactions, Taboos, and Warnings:

• Drug Interactions:
  • Anticoagulants/Antiplatelets (e.g., warfarin, aspirin): Theoretical risk due to Vitamin C content and possible antiplatelet effects; monitoring is advised.
  • Diuretics: High Vitamin C doses may interact with loop diuretics like furosemide.
  • Aluminum-containing antacids: Vitamin C may increase aluminum absorption; separate administration by 2-3 hours.
• Contraindications (Taboos): Known allergy to roses (Rosaceae family). Safety not fully established in pregnancy/lactation; caution advised.
• Warnings/Side Effects: Generally well-tolerated. High doses may cause mild GI discomfort (nausea, diarrhea, heartburn), headache, or insomnia due to high Vitamin C/bioactive load. Individuals with kidney stones (oxalate) should use cautiously.

1. Applications:

• Nutraceuticals & Functional Foods: Powder and extracts widely used in capsules/tablets for joint health, immune support (Vitamin C), and general wellness. Incorporated into teas, jams, and health beverages.
• Cosmeceuticals & Skincare: Seed oil and extracts are prominent in anti-aging serums, moisturizers, and after-sun products for regeneration and antioxidant protection.
• Clinical Nutrition: Used as an adjunct in managing osteoarthritis and for nutritional support in conditions with high oxidative stress.
• Animal Health: Studied as a natural anti-inflammatory and antioxidant supplement in pet food, particularly for aging dogs with joint issues.
