Francis Bacon wrote that borage had “an excellent spirit to repress the fuliginous vapour of dusky melancholie.”
John Gerard’s Herball mentions an old verse concerning the plant: “Ego Borago, Gaudia semper ago (I, Borage, bring always courage)”. He states that “Those of our time do use the flowers in sallads to exhilerate and make the mind glad. There be also many things made of these used everywhere for the comfort of the heart, for the driving away of sorrow and increasing the joy of the minde. The leaves and floures of Borage put into wine make men and women glad and merry and drive away all sadnesse, dulnesse and melancholy, as Dioscorides and Pliny affirme.
Syrup made of the floures of Borage comforteth the heart, purgeth melancholy and quieteth the phrenticke and lunaticke person. The leaves eaten raw ingender good bloud, especially in those that have been lately sicke.” Borage is used in companion planting.
It is said to protect or nurse legumes, spinach, brassicas, and even strawberries. It is also said to be a good companion plant to tomatoes because it confuses the mother moths of tomato hornworms or manduca looking for a place to lay their eggs. Claims that it improves tomato growth and makes them taste better remain unsubstantiated.
