My Sunflower Seed Milk is amazing I make the same way you make homemade almond milk by blending the seeds with milk then straining.
To the blender with the strained Sunflower Milk and I blend it together. Amazing 
Sunflower Seeds are high in Magnesium and therefore have a calming effect on the mind. Try making it yourself one afternoon, for a nice plant based beverage. It’s delicious
