Yes, some species like Laminaria japonica (kombu) are edible and used extensively in East Asian cuisine.
When dried and sterilised, the stems are hygroscopic (absorb water) and expand slowly, providing a gradual and physiological method of cervical dilation.
No, it is a highly specialised term used almost exclusively in scientific (marine biology) and medical fields.
