Kava can damage the liver at a high enough dose, badly enough that some countries have banned it. Herbal is not a synonym for gentle.
The unnerving part is how quiet liver damage is. Someone self medicating anxiety with kava can be accumulating harm and feel nothing at all until it is well advanced. If you or someone you support is taking it, that belongs in a conversation with a doctor rather than in a private routine.
Qur’an and Sunnah
Eat from the good things We have provided for you, but do not overstep the bounds (Quran 20:81). The permission and the limit arrive in the same sentence.
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
Set that risk against what the benefit side looks like. An international psychiatric taskforce that reviewed nutrient and plant based treatments placed most supplements for ADHD in the weak or provisional category. A real risk sitting opposite a benefit that has not been established is not a good trade.

Strength of evidence: one line of research. A single study, or a theoretical account.
Why it works
Its active compounds are toxic to liver tissue, and the liver does not complain early.
When not to
Anyone taking kava regularly should have their liver function checked by a doctor.
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
Sensory integration training is popular and it does not help ADHD. Whatever value it has elsewhere, the capacity it works on is not the one that is impaired here.
When a parent is set on something that will not hold, one honest story often lands better than a pile of studies. A family finished the better part of a year of neurofeedback and watched their child slide back to where he started within weeks.
Ask which direction a person's sensory difficulty runs before offering anything. Someone who is under responsive needs more input and someone who is over responsive needs less, and the wrong one makes the day harder.
