The Friends star reposted an educational video from the organisation, encouraging her followers to donate for Giving Tuesday.
The actress added that the charity plans to match donations eight times over during this global generosity movement.
Jennifer’s Instagram posts are among her first since she paid tribute to her late friend and former co-star, Matthew Perry.
In the original post, the organization continued: “We are grateful for our donors and local partners who make it possible to deliver critically needed medicines and supplies to 85 countries on average each year. Give the gift of #health this #GivingTuesday.”
Jennifer told her 45 million followers: “Their funds deliver critically needed medical aid and mental health support to survivors of crisis and frontline healthcare workers around the world.”
This post came just two weeks after she paid tribute following the tragic passing of her Friends co-star and friend Matthew Perry.
