Collect the flower in early summer (May and June flowering). Cover the freshly picked flower heads with boiling water and leave to cool. Take the solution and use a dropper or cotton bud to apply to your eyes. I used this 2 days ago, it works and is an old and I thought well known remedy. Also for cats and dogs with conjunctivitis. Putting vinegar in your eyes just sounds silly. Sambus flowers are very antiseptic. The same thing with a cooled solution of sugar and water poured over the flowers and left for 48 hours makes a wonderful cordial. This eventually will form a alchoholic drink if left to ferment as the flowers supply their own favourable yeasts.
