Two to be careful with in particular. Yohimbe reliably ramps anxiety up, so much so that it has been used in research to bring panic on, and kava is a sedative that stacks with alcohol and with sedating medication and has damaged livers at higher doses.
Kava has been restricted or banned in several countries over liver harm, which tells you how seriously that risk is taken. Yohimbe is a poor choice for anyone anxious, which is often exactly the person reaching for it. And if you are already taking something sedating, or drinking, kava is the wrong companion for either.
Qur’an and Sunnah
Eat from the good things We have provided for you, but do not overstep the bounds (Quran 20:81). The warning is about the amount and the crossing of a line rather than about the thing itself.
كُلُواْ مِن طَيِّبَٰتِ مَا رَزَقۡنَٰكُمۡ وَلَا تَطۡغَوۡاْ فِيهِ فَيَحِلَّ عَلَيۡكُمۡ غَضَبِيۖ وَمَن يَحۡلِلۡ عَلَيۡهِ غَضَبِي فَقَدۡ هَوَىٰ
‘Eat from the good things We have provided for you, but do not overstep the bounds, or My wrath will descend on you. Anyone on whom My wrath descends has truly fallen

What the research says
Even practices with genuine reported benefits carry risks in some people, and honest reviews say both halves. A review of the psychological effects of fasting beyond 24 hours describes the mood elevation people report alongside the risks in vulnerable groups. That double statement is what you want from any account of a remedy, and it is usually missing from a label.

Strength of evidence: one line of research. A single study, or a theoretical account.
Why it works
Both do something strong and specific in the body, so stacking them with alcohol or with medication pulling the same way makes the effect bigger rather than safer.
When not to
Anyone with liver problems, or taking sedatives or antipsychotics, should avoid kava entirely and check with a pharmacist.
This one is still a draft. It is waiting on a scholar and a clinician to read it before it is published.
Near this one
When something has gone wrong across several systems, expecting one treatment to fix it is usually the mistake. Movement, processing what happened, changes to food and work on calming the body tend to add up in a way that none of them manages alone.
Allergies turn up more often alongside ADHD than chance would predict. Worth mentioning your allergy history at an assessment even when nobody asks, since the two seem to travel together.
Gluten free and dairy free eating is essential in coeliac disease and in a genuine milk allergy. Neither one treats ADHD, and putting a child on them without a reason carries costs of its own.
