If you want to use herbal remedies, two things carry most of the risk. Make sure whoever prescribes for you knows what you are taking, and buy from a source that has been independently tested.
That is a short list on purpose. Nearly all the harm in this area comes from an interaction nobody knew about or a product that was not what it claimed to be, and both are avoidable before you swallow anything. Beyond those two, whether a particular herb helps you is a fair thing to try and find out. Nobody has to give up on the idea to be sensible about it.
Qur’an and Sunnah
People, eat what is good and lawful from the earth (Quran 2:168). Two conditions rather than one, and a remedy that comes from a plant still has to meet both.
يَٰٓأَيُّهَا ٱلنَّاسُ كُلُواْ مِمَّا فِي ٱلۡأَرۡضِ حَلَٰلࣰ ا طَيِّبࣰ ا وَلَا تَتَّبِعُواْ خُطُوَٰتِ ٱلشَّيۡطَٰنِۚ إِنَّهُۥ لَكُمۡ عَدُوࣱّ مُّبِينٌ
People, eat what is good and lawful from the earth, and do not follow Satan’s footsteps, for he is your sworn enemy

What the research says
Getting the details right is what decides whether a benefit turns up at all. A meta-analysis of double blind placebo controlled trials found omega-3 improved depression, with EPA predominant preparations outperforming DHA ones. The same nutrient, prepared differently, gave different results. That is the whole argument for knowing your source and telling your prescriber what is in the cupboard.

Strength of evidence: one line of research. A single study, or a theoretical account.
Why it works
The two failures that actually hurt people are an unknown combination and an unverified product, and both are settled in advance.
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
Stimulants sharpen focus in almost anyone, so responding well to one does not confirm you have ADHD. The diagnosis comes from your history and how you function, not from a trial of tablets.
Skin prick and IgE blood tests find real allergies. The IgG food sensitivity panels sold direct to families have not been shown to measure sensitivity at all, and they tend to come back with a long list of foods to avoid.
Months of fog, where thinking feels like wading, is a real complaint and deserves looking into rather than waving away. It usually has more than one cause, which is part of why it gets dismissed.
