Welcome to Just Answers. I am here to try to help.
This plant is part of the rose family and bears yellow fruits with seeds. This was an interesting one to research!! Many different opinions.
The seeds of this plant do contain cyanide in small amounts -- the leaves etc are associated with some other toxicity. The fruits apparently are edible.
If large amounts of the seeds were opened and chewed -- possibly it would be a problem. Poison control stated that the seeds will pass through the body undigested and do not pose a problem in small quantities.
You should be fine --
