I haven’t heard of any.

I took agnus castus for breastfeeding to help create more flow.

I didn’t are them. But I suggest you be careful taking them. A lot of natural products can be quite harmful when not taken correctly

Have never tried these but have read numerous times how the real whole food is better than an extract or supplement for any ‘natural’ remedies. SO if there is any benefit of raspberries beyond their normal health promoting properties then eating them fresh might be best. Some preparations may contain additives and tinctures alcohol which you would not want to pass on through breast milk.
