Sida Cordifolia and Dyphylline

Here is the interaction we found between these two, with the evidence behind it.

Major

METHYLXANTHINES

Why this applies to Dyphylline

Dyphylline falls under METHYLXANTHINES — the group Sida Cordifolia interacts with.

Theoretically, Sida cordifolia might increase the risk of serious adverse effects when taken with methylxanthines.
Sida cordifolia contains ephedrine. Use of ephedrine-containing herbs with caffeine or other methylxanthines such as theophylline might increase the risk of stimulatory adverse effects. Some clinical research and case reports suggest that using ephedrine with caffeine might increase the risk of serious life-threatening or debilitating adverse effects such as hypertension, myocardial infarction (MI), stroke, seizures, and death.
Severity Major Likelihood Probable Evidence D

Interaction has not been documented in well-controlled studies, however, the interaction has been demonstrated in some small human studies or in controlled animal studies in conjunction with multiple case reports..

Dr. Brian Staiger, PharmD, BCPS
Dr. Brian Staiger explains PharmD, Clinical Pharmacist

Here's the thing with this combo: Dyphylline is a methylxanthine, in the same family as theophylline and caffeine. It's already a mild stimulant to your system. Sida cordifolia naturally contains ephedrine, which is also a stimulant. Stacking two stimulants together is where the worry comes in.

When you pair them, the stimulant effects can pile on top of each other. That could mean a racing or pounding heartbeat, a jump in blood pressure, jitteriness, trouble sleeping, or nausea. In serious cases, people have had dangerous events like very high blood pressure or heart rhythm problems. To be fair, the evidence here is mostly anecdotal and theoretical, not proven. Still, since both push in the same direction, I'd play it safe. Please check with your pharmacist or doctor before combining these.

About Sida Cordifolia

What is Sida Cordifolia?

Sida Cordifolia
  • Weight loss and energy
  • Asthma and breathing problems
  • Joint and muscle pain
  • Fever and cough
  • General fatigue or 'tonic'

Sida cordifolia (bala or country mallow) is a traditional Ayurvedic plant that naturally contains ephedrine, a powerful stimulant. Because of this, many supplements containing it have been banned or restricted, and it carries real risks to the heart and blood pressure. There is little reliable human evidence that it works, so most people should avoid it and talk with a pharmacist or doctor first.
