Herbal Options for Anxiety and Depression: 5-HTP, St. John's Wort, and Safety Considerations

Natural antipsychotics don't exist, but several herbs help anxiety/depression. Critical: never combine 5-HTP and St. John's wort (serotonin syndrome risk).

5-HTP (5-Hydroxytryptophan)

• Mechanism: Direct serotonin precursor.
• Dose: 50–100 mg 2–3× daily with food.
• Use: Depression, anxiety, insomnia, fibromyalgia.
• Cautions: Never with SSRIs, SNRIs, MAOIs, tramadol, St. John's wort. May cause GI upset.

St. John's Wort (Hypericum perforatum)

• Mechanism: Weak MAO/COMT inhibition, serotonin/dopamine/norepinephrine reuptake inhibition.
• Dose: 300 mg 0.3% hypericin 3× daily (standardized).
• Use: Mild-moderate depression.
• Cautions: Induces CYP3A4 – reduces levels of OCPs, warfarin, cyclosporine, antiretrovirals, many others. Photosensitivity.

Safer Alternatives for Anxiety

• Passionflower (Passiflora incarnata): 250–500 mg or 2 mL tincture 3× daily. GABAergic, non-sedating at low dose.
• Kava (Piper methysticum): 70–250 mg kavalactones. Effective for GAD. Liver toxicity risk – use only noble root, water extract, <4 weeks, monitor LFTs.
• L-theanine: 100–200 mg. Calm focus, no sedation.
• Lavender oil (Silexan): 80 mg daily. Clinically proven for anxiety.

Grounding Herbs

Adaptogens (ashwagandha, rhodiola) build resilience over weeks. Not acute "grounding."

When to See a Professional

Suicidal thoughts, psychosis, bipolar, severe functional impairment. Herbs complement, not replace, psychiatric care.

Choose one, start low, track mood daily, inform all providers.
