For other people who have no idea what LSA is...

LSA is a 3 in 1 solution [...] made of ground linseed, ground sunflower seeds and ground almonds

Seems to be a thing in Australia and New Zealand.

And just because I didn't know this until yesterday, Linseed is Flax seed, just different names for the same stuff.

You can use your kitchen grade flaxseed oil for painting, putting your art supplies linseed oil on your quark is more questionable.

I used to use it on my cricket bats all the time, and nowadays on my Kendo Shinai.

I guess it is one of those oils like Coconut oil, where you can ingest it or use it for a myriad of lubricating and protective purposes.

Apparently the ground linseed/flax loses its goodness (major non-fish source of omegas) very quickly after grinding unless refrigerated. So the store bought LSA is no good. You need to grind it yourself and either eat it immediately or keep it in the fridge. Apparently it has a magical smell when ground.
