Have you ever found yourself staring at the supplements aisle, wondering if there’s a natural fix for stress or depression? You’re not alone. St. John’s Wort (Hypericum perforatum) has earned a reputation as a go-to herbal antidepressant. But is it really safe?
Spoiler: It’s more complicated than it looks on the bottle. Let's explore what makes this herb both helpful and potentially harmful—and how to use it safely (if at all).
What Is St. John’s Wort Used For?
This flowering plant has been used for centuries to ease emotional distress and boost mood. Today, it’s best known for treating mild to moderate depression and sometimes anxiety or sleep issues.
Many users report:
-
A noticeable lift in mood
-
Reduced anxious thoughts
-
Mild improvement in sleep
Sounds good, right? But keep reading—there are some red flags you need to know.
Drug Interactions to Watch Out For (Seriously)
Here’s where things get risky. St. John’s Wort alters how your liver processes many medications. That means it can reduce or enhance the effects of other drugs—often in dangerous ways.
High-Risk Drug Interactions Table
| Medication Type | Potential Interaction Risk |
|---|---|
| Antidepressants (SSRIs, SNRIs) | Serotonin Syndrome (life-threatening) |
| Birth Control Pills | Reduced effectiveness → unintended pregnancy |
| Blood Thinners (e.g., Warfarin) | Increased clotting risk due to lowered drug levels |
| HIV Medications | Reduced effectiveness → viral rebound |
| Chemotherapy Drugs | Weakened cancer treatment effects |
| Immunosuppressants | Risk of organ rejection |

Don’t make the same mistake. Herbal doesn’t always mean harmless.
