Confirmed this item DOES synergize with Infusion and DOES work on a persistent basis.

This can be explained by the variables used. There're 3 variables related:


 * An HP multiplier: Initial value is 1(100%). Caps at 4(400%, where the number in the infobox above comes from). This variable is only influenced by Bitter Root. Whenever you pick up one more this item, 0.08(8%) is added to the multiplier. At the 38 stacks, this variable becomes 100% + 8% * 38 = 100% + 304% = 404% -> 400% (capped).
 * The 'base' max HP of the player: This variable is increased when your little buddy level up, gain health from Infusion (and maybe pick up a Colossal Knurl, needs to be confirmed). It can go beyond 9999.
 * The 'real' max HP of the player: This variable is the one shows on your health bar. It is an integer caps at 9999. Decimals will be rounded up to the larger integer.

Thus, we can easily conclude that your ['real' max HP] = ['base' max HP] * [HP multiplier]. There's no way of knowing your HP gain during the period of 3-4 Bitter Roots or HP gain from Infusion and then caluculate them separately.

So when you pick up another Bitter Root, the game increases the multiplier, times your base HP, rounds the product up to a integer, done.
