2/5 Evidence Score

ParActin® is a branded Andrographis paniculata extract from HP Ingredients, standardized for andrographolides. Two published placebo-controlled trials used ParActin. In 103 adults with mild to moderate knee osteoarthritis, 300 or 600 mg a day for 84 days lowered knee pain scores more than placebo and improved stiffness, physical function, fatigue and quality of life scores; HP Ingredients funded the trial and the lead author was affiliated with the company. In 60 adults with active rheumatoid arthritis, ParActin tablets for 14 weeks did not lower joint pain, the main outcome, significantly more than placebo. Studies of andrographis products not named as ParActin are cited only as references. Allergic reactions, including rare anaphylaxis, have been reported with andrographis products; safety in pregnancy has not been studied, and people taking immune-suppressing medicine should ask a doctor first.

Studied Dose 300 or 600 mg a day for 84 days in the knee trial; ParActin tablets (30 mg andrographolide each, per the European Medicines Agency summary) three times a day for 14 weeks in the rheumatoid arthritis trial.
Active Compound Standardized Andrographis paniculata extract (ParActin®, HP Ingredients) standardized for andrographolides; the tablets in the rheumatoid arthritis trial contained an extract with 30% total andrographolides.

Benefits

Knee joint comfort and mobility

In 103 adults with mild to moderate knee osteoarthritis, 300 or 600 mg of ParActin a day for 84 days lowered WOMAC pain scores more than placebo at days 28, 56 and 84, and also improved stiffness, physical function, fatigue and quality-of-life scores. It is a single trial, funded by HP Ingredients, which sells ParActin; the lead author was affiliated with the company.

Joint pain in a second ParActin trial

In 60 adults with active rheumatoid arthritis, ParActin tablets three times a day for 14 weeks did not lower joint pain significantly more than placebo, the main outcome. Tender and swollen joint counts and a disability questionnaire improved within the ParActin group. Chilean public grants funded the trial; Herbal Powers supplied the extract. This does not show that a supplement treats arthritis.

Fatigue scores

In the knee trial, scores on a fatigue scale improved more with ParActin than with placebo; this was a secondary outcome in adults with knee osteoarthritis, in a trial funded by HP Ingredients. A pilot in people with multiple sclerosis taking interferon beta used an andrographis extract that the paper does not name as ParActin, so it is not counted here.

Standardized andrographolide content

ParActin is standardized for andrographolides; the tablets in the earlier trial held an extract with 30% total andrographolides, and the European Medicines Agency summary lists 30 mg andrographolide per tablet. No published head-to-head comparison with a generic andrographis extract was found, so standardization alone does not show better results.

Mechanism of action

1

NF-κB pathway inhibition (lab)

In lab and animal studies, andrographolide blocked activation of NF-κB, a switch for many inflammatory genes, by binding directly to one of its proteins. No cited ParActin trial showed a matching change in inflammatory markers versus placebo.

2

Immune markers in a patient trial

In the rheumatoid arthritis trial, rheumatoid factor, IgA and complement C4 fell within the ParActin group. These are disease markers measured in patients, not evidence of an effect in healthy people.

Clinical trials

1
Knee osteoarthritis trial: ParActin, 103 adults, 84 days
PubMed

Randomized, double-blind, placebo-controlled trial; 103 adults with grade I to II knee osteoarthritis; ParActin 300 or 600 mg a day or placebo for 84 days (Hancke et al. 2019, Phytother Res)

103 adults with mild to moderate knee osteoarthritis.

Both doses lowered WOMAC pain scores more than placebo at days 28, 56 and 84, and improved WOMAC stiffness, physical function, fatigue and SF-36 quality-of-life scores. The study was funded by HP Ingredients, the supplier; one author was affiliated with HP Ingredients and another with a contract research organization.

2
Pain trial in an autoimmune inflammatory condition: ParActin, 60 adults, 14 weeks
PubMed

Randomized, double-blind, placebo-controlled trial; 60 adults with active rheumatoid arthritis; ParActin tablets (extract with 30% total andrographolides) three times a day for 14 weeks after a 2-week washout; funded by Chilean public grants (CONICYT/FONDEF, INNOVA CHILE CORFO), extract donated by Herbal Powers, authors declared no disclosures (Burgos et al. 2009, Clin Rheumatol)

60 adults with an active autoimmune inflammatory condition.

Pain intensity on a visual analog scale, the main outcome, fell more with ParActin than placebo, but the difference was not statistically significant. Tenderness and swelling counts, a disability questionnaire and SF-36 scores improved within the ParActin group, and an autoantibody, IgA and C4 fell. The authors call for a larger, longer trial.

Side effects and drug interactions

Common Potential side effects

Allergic reactions, including rare anaphylaxis and angioedema, have been reported with andrographis products. Stop immediately and get emergency help for rash with swelling, difficulty breathing or faintness.
In clinical studies of oral andrographis preparations, reported side effects were mainly mild to moderate digestive and skin reactions.
In a pilot of an andrographis extract that the paper does not name as ParActin, one person had a mild, short-lived rash.
Safety in pregnancy and breastfeeding has not been studied (European Medicines Agency assessment); avoid use while pregnant.
Andrographis is studied for immune effects, so people with an autoimmune condition or taking immune-suppressing medicine should talk to their doctor first. No published trial naming ParActin lasted longer than 14 weeks.
In a rat study described by the European Medicines Agency, andrographolide given for 48 days disrupted sperm production; anyone trying to conceive should ask a doctor first.

Important Drug interactions

Immune-suppressing medicines (after a transplant, or for an autoimmune condition): andrographis is studied for immune effects and has not been tested alongside these drugs. Talk to your doctor before using it.
Blood thinners and blood pressure medicines: in lab and rat studies summarized by the European Medicines Agency, andrographolide slowed platelet clumping and some andrographis extracts lowered blood pressure. Human interactions have not been studied, so check with your doctor or pharmacist before combining.
If you take regular prescription medicines, ask a pharmacist before adding andrographis.
