Not only should you save the seeds, but don't waste the plentiful blooms or leaves of the marigold. The leaves can be rubbed onto the skin to ease the pain and swelling of a bee sting. Make an infusion by soaking the petals in water, and use as a rinse to further lighten fair hair. (You can make a stronger infusion by placing the petals in boiling water, cover and remove from heat. Allow to sit for 30 minutes. Strain if desired to remove the petals.)
The marigold can also be used as a skin cleanser. Try the recipe below to get the most use from this plant.
Warm the oil in a double boiler - do not boil. Stir in the dried flowers, cover, and slowly heat for 30 minutes. Allow to cool and stir in the fragrant rose or orange blossom water. Keep in a covered jar or bottle.
Just one note though as in all things you are going to ingest. Make sure that the seeds or plants are organic and edible. You do not want to be eating something treated with all sorts of chemicals. The same goes with picking in your yard or elsewhere. Always know what you are picking and what is around.
Happy Spring all!
