The set contains fermented and potentized yarrow, chamomile, stinging nettle, oak bark, dandelion and valerian that increase the proliferation of beneficial fungi and bacteria, stabilize nitrogen, attract trace elements and stimulate the silica, calcium, potassium, phosphorus and sulphur processes.
