Allelopathy is a fascinating and perplexing topic that concerns the chemical interactions of plants. It has profound implications in agriculture and forestry where species are grown artificially in mixture, with no evolutionary history of co-existence. The topic of allelopathy is widely credited as commencing in 1937, when the term ‘allelopathy’ was coined by Molisch. However, the concept of allelopathy has been recorded since Greek and Roman times, became extremely controversial in the first half of the 19th century, and remains so today.

This book concerns a virtually unknown treatise by Justus Ludewig von Uslar, published in 1844, which emerges as the first book entirely devoted to the concept of allelopathy. The book provides the historical background to allelopathic knowledge, from antiquity to c. 1840. It also provides for the first time a biography of Justus Ludewig von Uslar, who is best known as the first Consul-General for Hannover in Mexico, and Director of the Mexican Company, a British venture mining company. In many ways von Uslar epitomises the tradition of the gentleman scientist of the 19th century. The book then offers a full translation into English of von Uslar's rare treatise, which foreshadows many ideas current in allelopathic research.

To account for this specific poisoning of the soil, we must suppose, that particular plants convey into the soil, through the channels of their reducent vessels, certain specific fluids, which in process of time saturate it, and thus render it incapable of furnishing those plants any longer with wholesome aliment; in fact, the soil becomes replete with fecal or excrementitious matter, and on such, the individual plant which has yielded it, cannot feed; but...

This plant is one of those of which I cut the roots from the stalks, and soaked them separately, and which imparted to the water none of the properties which it acquired from the entire living plant.
Pagina 5 - One good old custom is not yet left off, viz. , to boil fennel with fish, for it consumes the phlegmatic humour which fish most plentifully afford and annoy the body with, though few that use it know wherefore they do it. It benefits this way, because it is an herb of Mercury, and under Virgo, and therefore bears antipathy to Pisces.
