Severity Moderate Likelihood Possible Evidence D

Dr. Brian Staiger explains PharmD, Clinical Pharmacist

Here's the simple version. Auranofin (Ridaura) is a gold-based medicine for rheumatoid arthritis, and one of its known quirks is that it can make your skin more sensitive to sunlight, sometimes causing rashes or easier sunburn. Arrach is a folk herb that, like other goosefoot-family plants, has been loosely linked to sun sensitivity too. So the worry is that stacking the two could add up and make your skin react more to the sun.

I want to be honest about how soft this concern is. It's theoretical, based on how these plants behave rather than real cases in people, so I wouldn't panic. Still, since Arrach has little proven benefit or safety record, it's worth a quick chat with your pharmacist or doctor before combining them, and practice good sun protection either way.

About Arrach

What is Arrach?

Arrach
  • Painful menstruation
  • Nervous complaints
  • Digestive upset
  • Wound care
  • Insect repellent

Arrach (Chenopodium vulvaria) is a strong-smelling European herb that has been used in traditional folk medicine, mainly for menstrual and nervous complaints. There is very little modern scientific evidence to show that it works or is safe, so it is not recommended, especially during pregnancy or breastfeeding. Talk to your pharmacist or doctor before using any herbal product.

About Auranofin

What Is Auranofin Used For?

Brand name: Ridaura

Auranofin capsules — sold as both Ridaura and Auranofin — are used to manage active rheumatoid arthritis in adults. Specifically, they're for people whose arthritis hasn't improved enough with full doses of nonsteroidal anti-inflammatory drugs (NSAIDs) like ibuprofen or naproxen, or who couldn't tolerate those medicines.

It works best alongside a full treatment program — not as a stand-alone fix. It's important to know that it doesn't work quickly: you may not notice improvement for three to six months, and it cannot reverse joint or bone damage that has already occurred.
