Very interesting,
@panckage.
What type of kratom are you using: white vein, red vein or green vein kratom?
I tried kratom myself not so long ago (3 grams of Thai white vein kratom made as a tea), but noticed no effects. However, I need to experiment with different dose levels.
There is the odd report or two online of ME/CFS patients getting good results with kratom:
The Main Active Ingredients in Kratom Are:
•
Mitragynine (plus its metabolite
mitragynine-pseudoindoxyl) which are agonists of the mu-opioid receptor and delta-opioid receptor. Mitragynine also has effects on adenosine, alpha adrenergic and serotonin receptors. Ref:
1
•
7-hydroxymitragynine which agonises mu, delta and kappa opioid receptors.
Kratom and mitragynine have different effects depending on whether taken at low or higher doses:
However, as to the biochemistry behind these low or high dose levels, different sources say slightly different things:
Kratom Dosage Guidelines:
Some other kratom dosage guidelines:
White Vein, Red Vein And Green Vein Kratom:
As well as the kratom dose level, the type of kratom you buy (white vein, red vein or green vein) has a bearing on the effects you will experience:
Red vein kratom tends to have higher levels of 7-hydroxymitragynine than white vein. Ref:
1
Delta-Opioid Receptor Agonism Seems to Provide Neuroprotective Effects:
This study found that delta-opioid receptor agonism, but not mu-opioid nor kappa-opioid receptor agonism, protects neocortical neurons from glutamate-induced excitotoxic injury. See also
this study. This neuroprotection from glutamate induced injury seems to be mediated by the inhibitory effect of delta-opioid receptor agonism on NMDA receptor activation. Ref:
1
Mitragynine co-administrion with morphine seems to mitigate the tolerance build-up with chronic morphine treatment. Ref:
1 2 So this kratom ingredient has the potential for treating drug addiction.
These neuroprotective effects of delta-opioid receptor activation suggest that for ME/CFS purposes, it is the lower dose range of kratom (which some websites say activate delta-opioid receptors) that may work best. The low dose range of kratom is also energizing, which is presumably what you want in ME/CFS.
Delta-Opioid Receptor Agonism May Treat Pain Without Addictive Effects:
Targeting delta opioid receptor may reduce pain without causing addiction
