Phytocidal by Ortho Molecular Products

If you’re looking for a clinician-style herbal antimicrobial, this andrographis-centered blend fits adults working on microbial balance after travel, periods of gut upset, or frequent seasonal bugs. It’s a practical option if your hs-CRP (a general inflammation marker) tends to run high during flares and you want a trial outside of antibiotics. Plant-based eaters often like that it’s capsule-based, not tincture. If you need targeted treatment for a diagnosed infection, see a clinician first rather than self-treat.

Andrographis provides andrographolides (the bitter actives) that modulate immune signaling and have direct antimicrobial activity in lab studies; in human trials it can shorten common-cold duration by a few days. Cat’s claw contains oxindole alkaloids that downshift TNF‑alpha (an inflammation signal) and may ease joint and gut reactivity. Sweet wormwood provides artemisinin, a sesquiterpene long studied for parasite biology, used here for broad microbial pressure. Japanese knotweed adds resveratrol, an antioxidant that dials down NF-κB (the cell’s master inflammation switch) and can modestly lower hs-CRP in responders.

Use 2 capsules daily with food to limit nausea. Most people gauge benefit within 2 to 4 weeks; clinician protocols often run 4 to 8 weeks, then pause and reassess symptoms and labs like hs-CRP. Avoid long, continuous use without guidance. If you’re combining with probiotics, separate by a few hours. Hydration helps with the bitter herbs. If you feel a rapid die‑off reaction (worsening fatigue, loose stool), scale back and ramp up more slowly.

Pregnancy or breastfeeding: avoid. If you have liver disease or drink heavily, get baseline and follow-up ALT and AST (liver enzymes). Warfarin or other anticoagulants, or high-dose fish oil: resveratrol can add a mild antiplatelet effect, so coordinate with your prescriber and monitor for easy bruising. On immunosuppressants or biologics: cat’s claw can counteract them. Artemisinin interacts with some antimalarials and seizure meds. Upcoming surgery: stop 1 to 2 weeks prior.
