I would personally be hesitant to do anything while you are nursing, although I think what you mentioned above is harmless, but I don't know if that would be strong enough to kick a parasite infection in yourself.
We did Humaworm for our children ages 2-5, but my youngest just turned 3 this month and we are on our second round of Humaworm and have had HUGE success! My now 3 year old expelled TONS of liver flukes from our first cleanse that he must have picked up from the lake when we went camping. Their doses of herbs like Wormwood are smaller then say like Hulda Clark so it takes longer to clean the whole body. Being on round 2 we are already feeling better and it's definitely working!
Best of luck! Hope you find what you are looking for!
