CBD type and strength


This is my first post, so i hope I’ve done this correctly… Looking for some help for my mother who has had PD for nearly 10 years. The positive effects of her medication is decreasing and she now has periods of total freezing where she literally can’t do anything until it’s time for her next dose of meds. Have started CBD oil 5% but looking to increase this. CBD Brothers seem to sell bigger strength oils. Does anyone have any experience with CBD helping in this instance and what strength oil do you use? Also, what type of CBD is most beneficial? Indica, Sativa or a hybrid? Many thanks
