There are many herbs you can take that have a natural liver detox effect. Milk thistle and dandelion are the first two that come to mind.
When it comes to products to take, I like one called Livatrex Liver Cleanser. I've used it multiple times whenever I'm doing a liver cleanse. You could use it without goign through the whole cleansing process. I believe it is 100% organic, but you may want to double check on that. Good Luck!
