I find Global Herbs products very reliable, but havent used that particular one.
Am I right its a recent injury? Theres really no substitute for proper anti inflammatories (not that im implying you arent, but I dont see the point in feeding much else).
Hi I did use this on my mare when she had a suspected damaged tendon. I did also use homeopathic Ruta grav & calc phos. She is now back in full work and no issues. I would def use their products again, but I have no scientific evidence that it worked! I am really into herbs and always try to find fresh ones (i often give my mare some camomile before a show & find it works)...
