How to create an item that refreshes a potion effect after a set interval by holding it

Ok so the effect is being given to me at the correct intervals, problem is Regen 3 isnt even healing me and it kinda just stays there even though its at 0 seconds

Heres the code

package mod.mcreator;

import net.minecraftforge.items.ItemHandlerHelper;

import net.minecraft.entity.EntityLivingBase;
import net.minecraft.entity.Entity;

import java.util.HashMap;

public class mcreator_soulOfBodyItemInInventoryTick extends testenvironmentmod.ModElement 
{

    static double Counter1 = 0;

    public static void executeProcedure(java.util.HashMap<String, Object> dependencies) 
    {
        if (dependencies.get("entity") == null) 
        {
            System.err.println("Failed to load dependency entity for procedure soulOfBodyItemInInventoryTick!");
            return;
        }
        
        Entity entity = (Entity) dependencies.get("entity");
        
        if ((new ItemStack(((entity instanceof EntityLivingBase) ? ((EntityLivingBase) entity).getHeldItemOffhand().getItem() : null), (int) (1))
                .getItem() == new ItemStack(mcreator_soulOfBody.block, (int) (1)).getItem())) 
        {
            
            Counter1 = ((double) (Counter1 + 1));
            
            if ((Counter1 >= 320)) 
            {
                if (entity instanceof EntityLivingBase)
                    ((EntityLivingBase) entity).addPotionEffect(new PotionEffect(MobEffects.REGENERATION, (int) 120, (int) 2));
                Counter1 = ((double) 0);
            }
        }
        else

    }
