Zac Efron suffered a severe allergic reaction to poison oak during the camping trip in May 10.
The 22-year-old actor developed a rash caused by the plant after going cliff-jumping with his friends for Memorial Day weekend. Zac described the experience of having ‘worst’ poison oak since it was his first time of experiencing it.
When he had a horrible rash, Zac thought that he looked like a zombie from “Dawn of the Dead.”
