1. Anything that increases rapidity of action or function.
2. That which activates developing agents in x-ray film processing chemicals or increases alkalinity, or softens the emulsion in film.
[L. accelerans, pres. p. of ac-celero, to hasten, fr. celer, swift]

accelerator (aksel´ərātur),

n 1. a substance that increases rapidity of action or function.
n 2. a catalyst or other substance that hastens a chemical reaction (e.g., NaCl added to water and plaster to hasten the set).
n 3. a film-developing solution of potassium hydroxide or sodium carbonate used to enlarge the emulsion and to establish an alkaline medium.
accelerator, platelet thrombin,
n See factor, platelet 2.
accelerator, prothrombin conversion, I
n (factor V, labile factor, plasma accelerator globulin, proaccelerin, serum accelerator globulin), a substance that is considered by some to be a factor in serum and plasma that catalyzes the conversion of inactive prothrombin to an active form.
accelerator, prothrombin conversion, II,
n (extrinsic thromboplastin, factor VII, serum prothrombin conversion accelerator [SPCA], stable factor), a substance that is considered by some to be one of the factors in the blood that accelerates the conversion of active prothrombin to thrombin by thromboplastin. Vitamin K deficiency reduces the activity of this factor.
accelerator, serum,
n See factor V.

Q. What herbs are known to be helpful against Arthritis acceleration?

A. mind you- herbs most of the time contain the same medication that pills do but without an exact amount and accompanied with other materials. there is great danger in that area, here is a guide for choosing a herbal supplement that will give you some tips :
