Leo gives representatives of his sign a strong and powerful constitution, a strong, handsome and well-formed body, abundant vitality (the ruler being the Sun), good immunity and less susceptibility to illness than any other sign. The heart – is the most sensitive organ; heart complaints or disorders such as palpitations and fainting are often observed. Leos fall ill rarely, though they suffer greatly during an indisposition, but they recover their strength quickly (the exaltation of Pluto). They are sporting (Mars in kinship), but it is important for them not to overstrain, since the proud Leo considers it beneath his dignity to «drop out of the race» when tired. Attention should also be paid to the spine (Saturn in exile). Psychologically it is very hard on Leo when his achievements, the things he is proud of, go unnoticed; this stings him and gives rise to anger that harms the heart if Leo expresses it too violently, and leads to psychosomatic illness if he keeps it in. Leo finds it hard to keep to a diet. The plants of Leo: sunflower, camomile, echinacea, rose, blossoms of guelder rose, hawthorn and dog rose, marigold, geranium, immortelle, daisy, celandine, dandelion flowers, St John's wort, peony, French marigold, dahlia, carnation, asters, centaury, pheasant's eye. They are used in cases where the patient needs extra energy and vitality, and for ailments of the heart, the vessels and the chest.
