8. We mentioned (above, 2) that there are two steps of losh – adding the water and mixing the components together. We also mentioned the topic of whether one violates the issur of losh just by adding the water without mixing. However, with some mixtures, just adding the water causes the components to be sufficiently combined without any additional action. The Gemara says (זבחים דף צ''ד ע''ב ) that in such a case, just adding the water is an issur d’oraisa of losh.
9. Flaxseed. The above Gemara says if someone puts flaxseed into water, he violates the issur d’oraisa of losh even if he did not do any action of mixing since flaxseeds naturally clump together when soaking in water. This is paskened in Shulchan Aruch (סי' ש''מ סי''ב, מ''ב סי' של''ו סקנ''א, פמ''ג משב''ז סי' שכ''א סקי''ב ). See below (29) for some similar examples.
