is there is a demand for this? It helps in opening up receptor sites. Maybe if there is a strong enuff demand, Pioneer or John Deer will start harvesting it.
We used to get a fair bit of it down here years back. Was used fairly widely then but choice was fairly limited and some said it worked (though I think the "opening up receptor sites" is still out for debate) though mostly not great bang for your buck. Some guys down here up until fairly recently used similar products as part of a more hefty stack and believed it was worthwhile. IronMike
