Body brushing does stimulate the lymphatic system and promotes cell renewal. HOWEVER it's possible to do it wrong which can be counter productive to lymph drainage!
The most responsible utube video on the web that I've found for proper method to body brush the entire body (lots of pretend experts on Utube!) is in the link below
Brushing at least once per week is better than not at all
If I remember correctly the Lymphodema Support Network have a DVD on Lymphodema Massage. This massage involves gentle massage of the lymph nodes starting at the neck (where the lymph 'empties' into the veins) and then works down towards the affected limb. I think the idea is to clear a path for the lymph to follow going top down rather than 'forcing' the lymph through potentially constricted lymph vessels and nodes. Anyway worth taking a look at if you considering self massage.
