Arnica
Arnica montana is used topically and as homeopathic preparations for bruising, pain, and postoperative swelling. A 2021 meta-analysis of 18 placebo-controlled trials found homeopathic arnica has a small effect size that 'just misses significance' for preventing hematoma after surgery, comparable to NSAIDs. Individual RCTs show mixed results - some positive (facelift bruising, cruciate ligament swelling), others negative (hand surgery, wisdom teeth). German Commission E approves topical use. Evidence quality is generally low.

Vitamin D

Vitamin D is a fat-soluble vitamin that our skin synthesizes when exposed to the sun. It benefits us in many ways, from bone health to mood.
Type-II Collagen
1 shared condition · 9 outcomes
Type II collagen (CII) is a protein and component of joint cartilage. Oral ingestion of CII in its undenatured form may reduce autoimmunity to the body's own CII, resulting in less joint inflammation in instances of osteoarthritis and rheumatism.
Systemic Enzymes (Bromelain/Trypsin/Rutin)
1 shared condition · 6 outcomes
Systemic enzyme combinations (e.g., Wobenzym) contain bromelain, trypsin, and rutoside (rutin). Individual patient-level meta-analysis (6 RCTs, n=697): Oral enzyme combination (OEC) as effective as diclofenac for knee osteoarthritis pain and function (Lequesne index), with significantly fewer adverse events (7.2% vs 15.6%). RCT (n=150, 12 weeks): Wobenzym comparable to diclofenac in relieving knee OA pain. Narrative review (9 RCTs): OEC as effective as NSAIDs without NSAID-associated adverse events. Used for osteoarthritis, sports injuries, post-surgical recovery, and inflammation.
Stinging Nettle

Stinging nettle (Urtica dioica) is a perennial plant that can cause painful reactions when it comes in contact with the skin. It has been used for many years as a medicinal vegetable in the treatment of pain, bleeding, urinary tract diseases, and allergies.
S-adenosylmethionine
1 shared condition · 30 outcomes
S-adenosylmethionine (SAMe) is a metabolite in the body that helps maintain several important biological reactions. Low levels of SAMe in the body are associated with several conditions, including liver conditions, chronic kidney disease (CKD), coronary artery disease (CAD), depression, and neurodegenerative conditions like dementia and Alzheimer’s disease. Supplementation with SAMe might improve liver health and depression, but further high-quality clinical trials are needed to confirm those benefits.

Resveratrol is a bioactive molecule found in plant sources such as grapes, peanuts, blueberries, and, famously, red wine. Resveratrol has anti-inflammatory and antioxidant properties that benefit cardiovascular function, glycemic control, and lipid metabolism. Although it’s promoted for lifespan extension, there’s no evidence for this in humans and limited evidence in animals.
