Bishop's Weed and Enoxaparin

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

Moderate

ANTICOAGULANT/ANTIPLATELET DRUGS

Why this applies to Enoxaparin

Enoxaparin falls under ANTICOAGULANT/ANTIPLATELET DRUGS — the group Bishop's Weed interacts with.

Bergapten, a constituent of bishop's weed, has antiplatelet activity. Theoretically, bishop's weed might have additive effects with anticoagulant or antiplatelet drugs and possibly increase the risk of bleeding.
Some anticoagulant or antiplatelet drugs include aspirin, clopidogrel (Plavix), dalteparin (Fragmin), enoxaparin (Lovenox), heparin, ticlopidine (Ticlid), warfarin (Coumadin), and others.
Severity Moderate Likelihood Possible Evidence D

Interaction has been documented in animal or in lab research, or the interaction has been documented in humans but is limited to case reports or conflicting clinical research exists.

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

Here's the gist for enoxaparin (Lovenox), your injectable blood thinner. Bishop's Weed contains a compound called bergapten that, at least in lab studies, can keep platelets from sticking together. Since enoxaparin already slows your body's ability to form clots, putting the two together could in theory add up and raise your bleeding risk.

What that might look like: easy bruising, nosebleeds, bleeding gums, or bleeding at your injection sites that takes longer to stop. I'll be honest though, this concern is theoretical and based on how the plant behaves in the lab, not on real patient reports. Still, since you can't undo a Lovenox dose once it's in, it's smart to skip Bishop's Weed and check with your doctor or pharmacist first.

About Bishop's Weed

What is Bishop's Weed?

Bishop's Weed
  • Vitiligo (loss of skin color)
  • Psoriasis
  • Digestive complaints
  • Asthma and breathing problems
  • Kidney stones
  • Diuretic (increasing urine)

Bishop's Weed (Ammi majus) is a flowering plant whose seeds contain natural light-sensitizing compounds called psoralens, which have been studied mainly for skin conditions like vitiligo and psoriasis when combined with light therapy. The plant is potentially toxic and can cause severe skin and eye reactions when exposed to sunlight, so it is not something to take on your own. If you are interested in psoralen-based treatments, work with a dermatologist rather than self-treating.

About Enoxaparin Injection

What Is Enoxaparin Injection Used For?

Brand name: Lovenox

Enoxaparin injection is used to prevent deep vein thrombosis (DVT) — blood clots in the legs — in people having abdominal surgery, hip replacement surgery, or knee replacement surgery, and in hospitalized patients who are largely immobile due to acute illness. It is also used to treat acute DVT, with or without a pulmonary embolism (a clot in the lungs), both in the hospital and at home.

It is also used alongside aspirin to reduce dangerous complications of unstable angina and non-Q-wave heart attack, and to treat acute STEMI (a severe type of heart attack involving full blockage of a coronary artery) in patients who receive clot-dissolving therapy or undergo a procedure to open the blocked artery (PCI).
