**Abstract**

At present, agricultural homoeopathy is being increasingly implemented worldwide to mitigate the negative effects caused by the indiscriminate use of chemical products in conventional agricultural practices. It is a viable alternative to improve organic agriculture, since homoeopathic medicines are innocuous substances with a capability to activate measurable response mechanisms when used in plants, animals and humans. Experimental research results allow us to conclude in this chapter that agricultural homoeopathy is able to stimulate favourable biological and even genetic responses in plants (basil *Ocimum basilicum* L., bean *Phaseolus vulgaris* L., cucumber *Cucumis sativus* L., tomato *Solanum lycopersicum* L.), which shows a novelty insight for organic agriculture.
