- Very high
- Why interaction risk is low
- Plant hairs and sap can trigger allergic contact dermatitis; avoid bare-skin contact and never pick or dig wild orchids.
- Why it is dangerous
- Lady's-slipper tissues bear contact allergens that can cause an itchy, blistering dermatitis in susceptible people.
- How to recognize a risky encounter
- Confirm the yellow pouch-shaped lip, twisted maroon-brown petals and sepals, and broad pleated stem leaves visually.
- What to do
- Do not touch or pick the orchid; wash exposed skin promptly and seek medical advice for a severe or spreading rash.
Responsible observation
- Identify: Look for a yellow slipper-shaped pouch among twisted dark petals.
- Protect: Keep the location undisturbed and photograph from firm established ground.
- Contact: Avoid touching leaves, stems, flowers, or sap with bare skin.
