Medicinal Plants: What They Are, How They Help, and When to Be Careful

Medicinal plants are herbs, roots, or extracts that people use to support health. From turning up the immune system to easing joint pain, these natural tools are popular because they feel safer than prescription drugs. But safety isn’t automatic. Some plants can thin the blood, raise blood pressure, or clash with medicines you already take.

Top Everyday Medicinal Plants and Their Main Uses

Here are five plants you’ll see a lot and what they’re usually taken for:

  • Ginger – good for nausea, digestion, and mild inflammation.
  • Turmeric (curcumin) – helps with joint comfort and overall inflammation.
  • Ginkgo biloba – used for memory support and circulation.
  • Devil’s Club – marketed for immune boost and pain relief.
  • Chenopodium oil – a newer supplement touted for skin health and antioxidants.

Each plant has active compounds that can affect the body’s clotting system. For example, ginger and turmeric contain natural salicylates, which act like a low‑dose aspirin.

Why Bleeding Risk Matters – The CRUSADE Bleeding Score Connection

If you’re on blood thinners, antiplatelet drugs, or have a condition that makes you bleed easily, you need to check the CRUSADE Bleeding Score. The score looks at factors such as age, kidney function, heart failure, and lab values. Adding a plant that also thins blood can push your score higher, meaning a bigger chance of bleeding complications.

When you add a medicinal plant, ask yourself:

  1. Does the plant have known antiplatelet effects?
  2. Are you already taking aspirin, clopidogrel, or warfarin?
  3. Do you have a recent bleed, low platelet count, or high creatinine?

If the answer is yes to any of those, talk to your clinician before you start the herb.

In practice, a doctor might lower the dose of your prescription blood thinner or suggest stopping the herb for a short period before a surgery. The goal is to keep the CRUSADE score in a safe range while you still get the plant’s benefits.

Here’s a quick cheat sheet for the most common bleeding‑related plants:

PlantBleeding EffectTypical Dose
Ginger (root)Low‑dose antiplatelet1–2 g fresh or 250 mg extract daily
Turmeric (curcumin)Moderate anti‑inflammatory, mild platelet inhibition500–1,000 mg extract with black pepper daily
Ginkgo bilobaIncreases platelet aggregation inhibition120–240 mg extract daily
Devil’s ClubLimited data, but contains coumarins that can affect clotting400–800 mg capsule daily
Chenopodium oilLittle evidence of bleeding impact1–2 tsp oil daily

Use this table as a starting point, but remember that supplement quality varies. Look for products that show third‑party testing and clear ingredient lists.

Bottom line: Medicinal plants can be a great addition to a healthy lifestyle, but they aren’t risk‑free. By checking how each herb interacts with your medications and by using the CRUSADE Bleeding Score as a guide, you can enjoy the benefits without upping your bleeding risk. When in doubt, ask a pharmacist or your doctor – it’s the fastest way to keep your health on track.
