They have a unique flavor that's reminiscent of asparagus or fiddleheads. Young leaves and shoots can be tossed in salads or cooked like other green vegetables.
What happens if dogs eat hops?
Compounds in the hops can cause a malignant hyperthermia, which results in a rapid rise of body temperature. A dog's body temperature, which is normally below 102°F (40°C), can rapidly rise to 108°F (42°C) or higher, potentially resulting in permanent damage to the organs and brain or even death.
Are hops poisonous to kids?

Can hops cause stomach problems?
But when the beer hits the stomach, it stimulates the release of gastric acid, an overabundance of which can lead to ulcers, acid reflux, and even stomach cancer. Now researchers report that the bitter acids derived from hops are key players in stimulating gastric acid secretion (J. Ag.

What are the constituents of hops?
The most characteristic constituents of hops are the bitter principles, known as alpha- and beta-acids. In the plant the alpha-acids occur as humulone, cohumulone, and adhumulone. 5, 6 During the brewing process, these compounds are isomerized to the iso-alpha-acid series of compounds, that possess the bitter taste. 7 The beta-acid series of compounds include lupulone and congeners; 5, 6 this series is destroyed during brewing. The relative proportions of the bitter acids affect the quality of the hops, and many methods have been developed for quantifying hop acids in different varieties, including nuclear magnetic resonance (NMR) 5, 8 and high-pressure liquid chromatography (HPLC). 9, 10 The complex profile of hop acids is dependent on genetics, cultivation, and storage conditions. Long-term storage of hops leads to major deterioration in quality.
