Poison Control, or a local emergency number
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.

What to expect at the emergency room
The health care provider will measure and monitor your vital signs, including temperature, pulse, breathing rate, and blood pressure. Symptoms will be treated as appropriate.
Note: You may not need to be seen in the emergency room.
How well you do depends on the amount of the substance swallowed and how quickly treatment is received. The faster you get medical help, the better the chance for recovery.
Recovery is very likely because chlorophyll is relatively nonpoisonous.
