Home Care

Wipe out the mouth with a cold, wet cloth. Immediately give the person milk to drink, unless instructed otherwise by a health care provider. DO NOT give milk if the patient is having symptoms (such as vomiting, convulsions, or a decreased level of alertness) that make it hard to swallow.

Wash the skin with water. If the plant material touched the eyes, rinse the eyes with water.

Determine the following information:

• Patient's age, weight, and condition
• Name of the plant
• Time it was swallowed
• Amount swallowed

Poison Control

The National Poison Control Center (1-800-222-1222) can be called from anywhere in the United States. This national hotline number will let you talk to experts in poisoning. They will give you further instructions.

This is a free and confidential service. All local poison control centers in the United States use this national number. You should call if you have any questions about poisoning or poison prevention. It does NOT need to be an emergency. You can call for any reason, 24 hours a day, 7 days a week.

Wearing gloves, place the plant in a container and take it with you to the hospital, if possible.

What to Expect at the Emergency Room

The health care provider will measure and monitor the patient's vital signs, including temperature, pulse, breathing rate, and blood pressure. Symptoms will be treated as appropriate.

Outlook (Prognosis)

Plants containing oxalic acid may cause swelling severe enough to block the airway, but this is very rare.
