Historical perspective: Dr. Majid Ali archive

Historical perspective drawn from the authorized writings of Dr. Majid Ali, preserved in the Clarkson archive. Shown for context; it is not current medical guidance.

Simple Remedies | Pradaxa for Blood-Thinning vs. Spices for Blood Cleansing 2014-10-17
Source of the quoted line. Its proposal of spices in place of blood thinners is rejected outright.
Dr. Ali's Book on Ethics and Philosophy of Medicine | RDA: Rats, Drugs, and Assumptions 2014-11-05
Source of the carried habit: ask what assumption sits under a recommendation. Its high-dose reading is held.
Green Tea 2014-05-27
Named for transparency; a clinical-hold record. Not carried.
Herbal teas for various health problems 2015-04-22
Named for transparency; a clinical-hold record. Not carried.

Claims we deliberately did not carry

That spices can serve as an alternative to an anticoagulant such as Pradaxa (dabigatran).
Rejected outright, not held for judgement. Never replace a prescribed medicine with a supplement without your provider's approval,³⁴ and changes in what you take can tip warfarin into bleeding or clots.²⁹
That green tea and herbal teas address a range of named health problems.
Held on cancer-claim grounds in the source inventory. Not carried; the page does not discuss green tea extract as a product.
That RDA methodology is unsound enough to justify dosing above standard intakes.
The question "what assumption sits under this recommendation?" is carried as a habit. Taking too much of some supplements is one of the ways problems start.⁷

Safety wording awaiting sign-off

The 'When to get help now' list is ProperHealth safety wording. Each line cites the official guidance it follows, and those passages are listed above with the other claims. The wording still needs pharmacist sign-off before public use.
