> The researchers also found snack items, such as dried blackberries, raspberries, grapes and flax Some can be snacks but its main purpose could be very different. Flax seeds are tiny and really not so valuable as snack, but you can powder them and obtain a very fine oil to use in lamps. In a six month dark winter or in a ship this can be more than a luxury. You could also save them for culturing at home and obtain a source of fine and durable clothes. Almond oil can be used in skin care to alleviate the effect of the cold in the face. Can be used also in candles. Flax oil can be used also in another very important thing in a wooden ship, to protect the wood and made it shiny, more durable and waterproof. Henbane is the outlier but could be used externally and its purpose in navigation is fascinating. Rare in the North but can be found in central and southern Europe if you know what to look for. Is not a creature that you should underestimate or play with but Vikings really don't need to navigate a lot to find it. The dried berries are all European crops. Maybe their purpose was to acquire valuable varieties of crops. May be used also to dye clothes.
