Lily of the valley / Convallaria majalis

A slender plant with fragrant white flowers, lily of the valley acts on a weak heart to improve its functioning. A potent medicinal herb, it can have toxic effects.

Limeflower, Linden blossom / Tilia spp.

Commonly planted in gardens and parks, the lime or linden tree bears flowers that perfume the air on summer evenings. The delicate scent acts much in the same way as the infusion made from the flowers, soothing troubled states of mind and relieving tension headaches, migraines, and sinus congestion.

Linseed or flax oil

Flax or linseed oil contains uniquely high levels (typically around 55 percent) of a-linolenic acid, an omega-3 polyunsaturated fatty acid similar to those found in fish oils. Plant-derived omega-3 oils are not so readily available for use by the body as fish oils, but nevertheless provide similar health benefits. All omega-3 oils have a protective activity on the heart and circulation and against cancer.

Lemon / Citrus limon

One the most useful home remedies, lemon works well in a host of common complaints. The traditional drink of lemon and honey can be spiced up with ginger and garlic to make a potent brew for colds, flu, coughs, and digestive disorders. Overall, the fruit improves resistance to infection.

Linseed, Flax / Linum usitatissimum

Grown as a food crop in temperate climates, linseed, or flax, is a valuable and readily available dietary supplement. A rich source of protein and omega-3 oils, linseed also contains high levels of phytoestrogens—roughly 10 times more than other seeds, making it a key remedy for menopause.
