Chakras for physical disease, not something like OCD. And Shael, OCD is not to do with Virgo, I know someone with it but has no Virgo. If anything, a lack of Virgo-like tendencies can result in over-correction, sort of like how someone completely lacking in Air can express Air tendencies but in a slightly different way. Actually come to think of it my friend who had OCD is low on Air, which could explain this, as Air helps to detach and be more spontaneous, whereas OCD indicates being strongly "stuck" in the habits.
OCD can come from a shitty childhood. Having no sense of control or accomplishment, needing to do something perfect and repetitively for the compulsive sense of perfection or satisfaction. As one example.
This Thursday, waning Moon in Virgo is a perfect date to do a freeing the soul working to remove this issue. Ansuz might be the best choice, for however many reps of it you can easily manage (don't ever strain yourself with vibrations), keeping in a multiple of 4 (Ansuz's number). Affirmation something like "I am now totally and completely free from obsessive and compulsive habits, in beneficial ways for me." You can even add something like "I am perfectly healthy and normal in every way now".
Another thing you can do, is distractions. This helped my friend who had it, they changed up their life a bit and became more able to "forget" to do things compulsively.
Yellow might be a good color to use for this, overcoming addictions and breaking habits:
