So sorry about Max and Michelle.
Glad you were able to get some
DMG since that is said to help with seizures. Here are some more natural remedies - note they are for humans:
Skullcap (Scutellaria lateriflora). Usually used as a tea or tincture, but can get powdered skullcap in capsule form. Skullcap seems to act upon benzodiazepine GABA receptors in the brain. GABA is a neurotransmitter that helps prevent over stimulation of the nervous system. If it gets too low you can have seizures, epilepsy, anxiety, depression, insomnia and more. Skullcap is an antispasmodic. It eases muscle twitches, spasms and seizures by relaxing the muscles, relieving involuntary muscle movements, and calming the nervous system. Warning: Use skullcap sparingly in small doses. Large doses may be harmful or could cause liver damage.
Valerian root (Valeriana officinalis). Valerian has a relaxing effect on the muscles of the body. For regular use (to prevent attacks), usual dosage for a human is between 100mg to 1 gram of dried and powdered root. Start with a low dose, depending on the person's size and the severity of the disease, and increase it gradually until you find a level that works. It can also be used for acute attacks. Warning: In ordinary doses, Valerian exerts a quieting and soothing influence upon the brain and nervous system. However, in large repeated doses, it can produce pain in the head, heaviness and stupor. It can become addictive, only use when needed.
Mugwort (Artemisia vulgaris) and Western Mugwort (Artemisia ludoviciana). The sedative effects of mugwort help ease epilepsy and convulsions. It has antispasmodic properties and can control seizures in some epileptics. It helps decreqse the severity of the seizures and increases the time between attacks. Tea or tincture of the leaf seems to work best. Warning: The plant may be toxic when used in large doses.
Thyme (Thymus vulgaris). Thyme has anti-spasmodic properties and prevents and treats epileptic seizures in some people. Oil of Thyme of Thyme Tincture are the best products to use for this purpose.
Looking around on the internet for natural remedies for seizures in humans, I found
vitamin B6, magnesium, vitamin E, manganese, taurine, (maybe disregard the vitamins and minerals if she's getting supplements)
dimethylglycine (
DMG which you've already got), and
omega-3 fatty acids (I would say this is an important one, provided by flax oil, or freshly ground flaxseeds - can do this in a dedicated small coffee grinder - chia seeds, walnuts).
Also
CBD oil. A study published in Epilepsia found that CBD improved the effect of clobazam, a benzodiazepine used as an add-on treatment for seizures in both children and adults. A US vet uses CBD oil for pain in parrots particularly for nerve pain (in Avian Ganglioneuritis).
Would she eat pellets? Adding Harrison's High Potency to her diet for 6 months would plug any nutritional gaps.
