Hey!
Aloe Vera Gel is great for eczema. You can add a pinch of turmeric and neem powder / neem oil for better results.
You can soothe eczema with a Chamomile Tea tea ... just make a tea with dried leaves and apply it to affected areas using cotton. Leave it on for 20 minutes and wash off daily.
There are many other options including using Wrightia tinctoria for severe eczema. Dilute with Coconut Oil to aoid charring of skin if it is a concentrated oil.
Hope it helps!
Take Care
