how do i make a punch that heals any player who it touches?

local rp = game:GetService("ReplicatedStorage")
local Barrage = rp:WaitForChild("Stand8Remotes"):WaitForChild("BarrageHealHold")
local TweenService = game:GetService("TweenService")
local Debris = game:GetService("Debris")

local Health = 3 -- what i tried
local debounce = false

function leftSide(Character,Stand,Folder,armPart)
	local posY = math.random(1.25,1.75)
	local rotX = math.random(-5,1) 
	
	local Arm = script:WaitForChild("Arm"):Clone()
	Arm.CFrame = Stand:WaitForChild("UpperTorso").CFrame * CFrame.new((math.random(-170,-150)/100),(math.random(50,150)/100),-.2)
	Arm.Orientation = Arm.Orientation + Vector3.new(rotX,-math.random(7,15),0)
	Arm.Color = armPart.Color
	Arm.Size = Vector3.new(1,1,1)
	Arm.Parent = Folder
	Debris:AddItem(Arm,.4)
	
	Arm.Touched:Connect(function(Hit)
		if Hit:IsA("Part") or Hit:IsA("MeshPart") then
			if Hit.Parent ~= Character and Hit.Parent ~= Stand then
				print(Hit)
				local EHumanoid = Hit.Parent:FindFirstChild("Humanoid")
				
				if EHumanoid and not EHumanoid:FindFirstChild("ArmPunch") then
					print("attacking")
					local ArmPunch = Instance.new("BoolValue",EHumanoid)
					ArmPunch.Name = "ArmPunch"
					Debris:AddItem(ArmPunch,.1)
					
					local sound = Instance.new("Sound",Folder)
					sound.SoundId = "rbxassetid://2174934844"
					sound.Volume = 1
					sound:Play()
					Debris:AddItem(sound,.5)
					
					local wave = script:WaitForChild("Wave"):Clone()
					wave.Parent = Folder
					wave.CFrame = Arm.CFrame * CFrame.new(0,0,-1)
					wave.Orientation = wave.Orientation + Vector3.new(90,0,0)
					Debris:AddItem(wave,.25)
					
					local goal = {}
					goal.Size = wave.Size + Vector3.new(5,0,5)
					goal.Transparency = wave.Transparency + (1 - wave.Transparency)
					local info = TweenInfo.new(.25)
					local tween = TweenService:Create(wave,info,goal)
					tween:Play()
					
					EHumanoid:GetDamage(Health) -- also what i tried
				end
			end
		end
	end)
