Healicus: Natural Remedies, Herbal Medicine, and Drug-Supplement Interactions
Healicus is an evidence-led natural-medicine reference for adults who want to know what the literature actually says before they take anything. The catalogue spans five healing traditions, Western phytotherapy, Traditional Chinese Medicine, Ayurveda, nutritional therapy, and mind-body practice, and is organised by the everyday intents people actually search for: natural sleep aid, natural stress relief, energy and fatigue, immune support, and digestive health. Every entry is anchored to a peer-reviewed source: a Cochrane systematic review, an EMA HMPC monograph, an EFSA authorised health claim, or a major-journal randomised controlled trial published in NEJM, JAMA, Lancet, or BMJ.
The free drug-supplement interaction reference covers documented herb-drug and nutrient-drug interactions across the most common prescription medications. Compare ashwagandha and SSRI antidepressants, turmeric and warfarin, St. John's Wort and birth control, magnesium and antibiotics, melatonin and SSRIs, ginkgo and blood thinners, CBD oil and anticoagulants, vitamin D and statins, among 25 long-form evidence reviews on specific supplement-medication pairs and roughly 100 evidence-anchored entries across the catalogue. Free to use, no account required.
How the catalogue is organised
Every entry, herb, supplement, habit, or technique, is filed by intent and tagged by tradition and evidence strength. Cochrane reviews and EFSA authorised health claims rank highest; EMA HMPC monographs and major-journal RCTs follow. Entries without a qualifying anchor are not listed. This is deliberate: Healicus is an information-retrieval tool, not a medical device. We surface what the regulators and the peer-reviewed literature have already concluded, not novel therapeutic recommendations.

Free drug-supplement interaction reference
The interaction reference is publicly accessible without an account.
